What is Causing My Electric to Hum?

Have you ever had such a great day that when you are alone you begin humming or whistling a song you recently heard? That’s when you know that you are having a great day! But, unfortunately, hearing a hum coming from one of your electrical systems or outlets can ruin all that. Don’t let it!

Dimmer Lights
Did you know that when you use a dimmer switch, you are not actually dimming the energy. Instead it is being turned off and on so fast (many times per second) that our eyes don’t notice it. The hum from your switch could be caused by the constant switching of power on and off.

Outlets
If you tracked that hum down to one of your outlets, don’t ignore it! It could mean that a wire is no longer properly grounded or that too many volts are being carried over those wires. Give us a call to repair it!

Circuit Breakers
If you hear an electrical hum coming out of your circuit breaker box please contact us immediately. That could mean that your box is being overloaded with current, but is not shutting off properly the way it was intended.

If you wish to investigate the problem yourself, try shutting off the power entirely and then turning the breakers back on one at a time. This could narrow down the cause. We always recommend contacting a licensed electrician when dealing with the electrical safety in your home.

How to Choose the Right Outdoor Extension Cord

Extension cords … how we do love thee! But most Charlotte residents have not taken the time to truly understand our extension cords. Are they all made the same? Does the length matter, except for convenience? What makes one outdoor extension cord better then another?

Last blog we discussed “Outdoor Extension Cord Safety”. This time we’re going to explain how to choose the right extension cord for the job on hand.

IMPORTANT NOTES

UL symbol – These means that the cord has been approved by the Underwriters Laboratories.
W – Marked “For Outdoor Use” and their coatings have been designed to prevent moisture entry.
Gauge/Wires – The packaging on the extension cord should have a numerical rating. For example, 14/3 means It is 14 gauge and has 3 wires inside.

WHAT SIZE?

The smaller the gauge number, the thicker the wire is, and the more electricity it can handle. But at the same time, keep in mind that the longer distance the current will need to travel, the thicker the wire (gauge) will need to be. Which is why buying only the correct length that is needed for the job is a more safety cautious rule of thumb.

This may seem confusing, but choosing the right outdoor extension cord is important for your family’s safety. Especially if you will be using it to run an outdoor appliance that requires a lot of juice.

Douthit Electrical has been providing Charlotte with quality electrical services since 1990. If you find yourself relying on multiple extension cords, that could signal that it is time to increase the number of outlets in your outdoor area.

Outdoor Extension Cord Safety

Outdoor extension cords can be a blessing or our demise. So many Charlotte residents do not have enough outdoor outlets and rely on extension cords to bring the power outside with them during the summer months.

I’m sure you’ve seen them lying in a pile on driveways or garage floors, waiting to be stored away. Or perhaps they are dragged across yards to provide energy to power our outdoor tools or toys.

Extension cords can be a blessing, but only if we take the extra precautions of observing proper safety and common sense. If you find yourself relying on multiple extension cords, that could signal that it is time to increase the number of outlets in your outdoor area.

If you’ve ever compared an indoor to an outdoor extension cord, you’ve undoubtedly noticed the differences. The most obvious difference is the insulation that protects the outdoor cord from the elements. But most importantly, never use an indoor extension cord outside!

You may think that purchasing an extension cord is as simple as measuring the length you need, getting in the car, and finding one on sale. But just like anything else that poses a safety risk in our homes, there are specifications you’ll want to consider.

The most important information you’ll want to gather in advance is the length of cord you’ll need, and how much power you want it to safely be used for. We’ll be discussing how to understand the ratings of extension cords and tips on how to choose the “right cord” for the job you have in mind in our next blog “How to Choose the Right Outdoor Extension Cord.”

Why does my breaker keep tripping?

Indoor Home Open Electrical Breaker PanelIf you continually need to go down to the basement or to the garage to your electrical panel box, your breaker is trying to tell you something.

The most common reason a breaker keeps tripping is because you are constantly overloading the same circuit. The breaker is trying to keep you and your family safe, by warning you the only way it can … by interrupting the power usage on a circuit that has reached its safe limit.

Before resetting the tripped circuit breaker, unplug the items that are on that circuit. Once you’ve reset the breaker, consider allocating the energy usage over different circuits. If that is not a practical solution, Douthit Electrical can help you decide if an upgrade is the next step.

If this is the first time you’ve been left in charge of resetting the breaker, here are a few helpful hints on how to reset a circuit breaker.

A short circuit or ground fault is another reason a breaker might be tripping. There is usually a physical sign when this happens. It could be as obvious as a blackened area around an outlet or even the smell of burnt wires.

Has a new appliance entered your home? Appliances come and go, but our electrical system tends to stay the same. New appliances can sometimes mean it is time to update the electrical system.

Now that summer is approaching, air conditioners can take a heavy strain on our electrical circuits. Make sure that your home can handle the extra power needed to keep your home cool.

Why aren’t the outlets in my bathroom working?

It’s happened to most of us. We’ve just taken our morning shower … switch on the hair dryer and nothing happens. We turn it off and on and off and on until we finally give up. Now it’s time to find out what is to blame for this inconvenience.

The most obvious next step is to try the hair dryer somewhere else. Find another outlet that you know is currently working and plug in the hair dryer. Does it work now? If it does then you’re on your way to discovering the problem.

Go back to the bathroom and see if that is the only outlet not working in the room. All the outlets in your bathroom should be updated to GFCI. Check the button in the center to see if it needs to be reset. In some cases, outlets in the bathroom and kitchen are updated by installing a GFCI circuit breaker in the main electrical panel. If you are not sure what the importance of GFCI outlets in your bathroom is click here.

The next step is to see if you have a tripped circuit breaker or blown fuse. Locate your main electrical panel. Check to see if a circuit breaker needs to be reset or a fuse replaced. If that’s the culprit of your hair dryer misery, reset or replace and check on the outlet. If that has resolved the problem, good job! If this becomes a common occurrence, you will want to find out the reason for it. Douthit Electrical can help!

If that did not restore the power to the outlet, then we suggest giving us a call to do more troubleshooting of the problem.

Why is electrical wire in different colors?

Electrician Connecting WiresWe’ve all seen those shows. The bomb is ticking and the hero has to decide which wire to cut to stop the timer. Did the bad guy change the colors to make it confusing? Luckily in our homes, the wires have been color coded and installed to make things as easy as possible to make changes to our electrical system.

Types of Wire
Hot — The job of a “hot” wire is to deliver power to a destination.
Neutral – A “neutral” wire completes the electrical circuit.
Ground – A “ground” wire is a safety measure. Put simply, an electrical spike sends the extra power through the ground where it can cause a circuit breaker to trip.

Common Wire Colors Used by Certified Electricians
Black Wire is always hot.
White Wire is neutral (but can change to live if marked accordingly).
Green Wire is always a ground wire.
Red Wire is always hot and used more in switch wiring.
Yellow and Blue Wire is less common, but if used are hot wires.

Never guess or assume! Always shut off the power when working with electricity. All electrical home projects should be done carefully to ensure the safety of your home.

Always connect wires of the same color, and as an added precaution use insulated tools when working with or even around electrical wires. Remember to err on the side of caution when dealing with electricity.

My old dryer outlet was only 3 slots. What do I do?

Laundry Room DesignGas dryers require very little electrical power. They use gas as their heating power source and their electrical needs are mainly to turn the drum. They typically use the same 120V amount of power as a small appliance.

Electric dryers are quite different. Electric power is converted to heat and has much more power needs. These require an electric outlet that is specifically for dryers and the extra power they need to run properly.

3 Prong vs. 4 Prong
If your previous dryer was older than 2000, then it may have very well been quite happy with the 3 prong outlet in your home. Since that time, many electrical safety advances have been made. That is reflected in the current electrical code that requires 4 slots in newer home 220V outlets. The extra slot was an added safety measure to add an additional neutral path to the circuit.

What do I do?
Douthit can update your outlet to the new safety standards. Just give us a call for an appointment.

But, if you would like to wait to change to a 4 prong outlet, you may be able to convert the dryer cord yourself.

Changing the Dryer Cord
We always recommend having a licensed electrician help you with your home’s electrical projects, but if you are feeling confident, here’s our suggested steps:

1. ALWAYS MAKE SURE THE DRYER IS UNPLUGGED.
2. There should be a metal plate covering the area on the back of the dryer where the cord attaches. Remove it and make sure to put those small screws where they won’t be lost.
3. You should now see a restraint that keeps the cord stable and helps to relieve the stress and strain of movement. Remove the restraint.
4. Disconnect the existing dryer cord
5. Connect the center wire of the new 3 prong cord to the center silver terminal.
6. You have 2 wires on the new cord that now need be attached. Attach these to the 2 terminals beside the silver terminal.
7. Reattach the restraint collar. This can be frustrating and can take a bit of patience. Slide the tab ends one at a time into the cord wire hole. When you’ve been able to match up the 2 halves and can get the screws to catch, you’re done with the hardest part. Tighten.
8. Replace the safety plate.
YOU MUST GROUND THE DRYER. Return the frame ground strap to the central terminal post (neutral).

All electrical home projects should be done carefully to ensure the safety of your home. Always err on the side of caution when dealing with electricity.

Why is my light bulb flickering?

A flickering light bulb is more common that you might think. A slight drop in your Charlotte home’s voltage can cause your lights to dim momentarily … or flicker. Here’s a few things you can check before calling your local electrician.

Loose bulbs. Sometimes the easiest solution is the right solution. Make sure the bulb is not loose and is properly seated in the socket.

Type of Bulb: Fluorescent lights tend to flicker more often than the more energy efficient LED light bulbs. The easy answer is just to replace the bulb. Hopefully that will solve the problem.

Dimmer switches: Low voltage LED bulbs can often flicker on these types of switches. Dimmer switches expect to be controlling higher voltage items and can cause lower voltage bulbs to flicker.

Faulty connections: Sometimes a switch can go bad over time, as do most things in our home. See if the on/off switch has a bad connection and is causing the flickering. You should also check the outlet where it is receiving its power, to make sure the prongs are not bent or damaged.

Appliances: Our appliances can sometimes require a surge in power when they are in full operation. You may have noticed your lights flicker when your washer or another appliance turns on. If this is a common occurrence, you should consider calling an electrician to help you decide if your home’s circuit is being constantly overloaded.

These are just a few examples of common reasons why your light bulb could be flickering. If you experience a sudden change in your home’s electrical system, you should always err on the side of caution, and give your friendly electrician a call.

How do I remove a broken light bulb?

BulbA broken light bulb stuck in a light fixture can be much more trouble than you might expect. It is always best to approach anything dealing with electricity with the “better safe than sorry” point of view.

Preparation

  • Gloves
  • Goggles
  • Drop cloth to catch any broken pieces from the bulb that may shatter.
  • Make sure to turn off the power!

Methods

Pliers: Pull out any large pieces of the bulb left in the socket. Use needle nose pliers to hold onto the base of the bulb. Once you have a good grip, start twisting and pulling the bulb away from the socket to pull the bulb free.

Potato: You’ve probably heard of the “potato method” for freeing a broken light bulb. Yes, it can actually work. Grab a raw potato from the kitchen and cut off the end, insert it into the socket and give is a twist. That potato should actually give you a grip on the broken light bulb and hopefully free it from the socket. Please dispose of the potato after it has successfully done it’s job.

Hot Glue: For exceptionally difficult broken bulbs, apply a large dose of hot glue to a stick of wood that will fit into the bulb’s base. Completely fill the base with glue. After letting the glue set for over 5 minutes, use the wood stick like a handle to unscrew the bulb from the socket.

Remember: always be careful with any project dealing with electricity. Safety should always be your first concern!
