What is the difference between a surge arrester and a surge suppressor?

If you are confused by the uses of a Surge Suppressor, a Surge Arrester and a Lightning Arrester, you are definitely not alone. The differences between the 3 of them are similar but different at the same time.

All three of these have the same purpose, to keep unwanted electrical power from damaging your home and its systems. Whatever protects your home is definitely something that should be understood.

Surge Arrester
A surge arrester “arrests” unwanted power that enters your home from outside sources such as lightning, or surges from your power company. It sends that excess power directly into an installed grounding application.

Lightning Arrester
A lightning arrester “arrests” unwanted power from a lightning strike before it reaches your door and sends the power into the ground outside.

Surge Protector
A Surge Protector “protects” your home’s electrical system from power surges created inside your home. It is often intalled into the network in a whole home protection system.

Now you may be wondering if you need 1, 2 or all 3 of these. The best answer is to give Douthit Electrical a call. Everyone’s home and needs are different. We can discuss your options and recommend what we believe to be the right course of action for the safety of your home and its electrical system.

Why does my microwave keep tripping the breaker?

A microwave has become as essential in our kitchens as our stove top and oven. But because of its small convenient size, we often forget just how much power it takes to reheat those leftovers or cook those quick meals.

It’s because of this power that our microwave uses that it should be on its own dedicated circuit. This allows it to draw the essential energy it needs, without being hindered by other devices on the same circuit.

Microwave ovens have come a long way since 1970, and they now are available in all types of sizes and strengths. It is always a good idea to install a breaker that can handle a slightly higher amperage than your microwave lists it uses. Giving the appliance room for a bit of fluctuation is always a good idea for safety and future peace of mind, especially if your breakers are older.

Step One – Test Microwave
First, let’s be sure the microwave is functioning properly. Use the microwave in an area of the house that is guaranteed to not be on the same circuit, a garage or workshop perhaps. If it works then go on to step 2. If it does not, then the microwave is faulty.

Step Two – Check the Circuit
Locate your circuit breaker box and look to see if it is on its own dedicated circuit. Hopefully your box is sufficiently labeled to make this an easy chore. If the circuit is shared with other items, then a dedicated circuit for the microwave is what is needed. If it appears to already have its own dedicated circuit, then a higher amperage may be required. Douthit Electrical can examine the circuit and recommend a course of action with your family’s safety in mind.
