What to do when motion lights won’t turn off

Motion lights are a great addition to a home. They not only add safety and security, they add convenience. No longer do you need to remember to leave lights on outside (and waste power), you can be confident that they will turn on when they are needed most.
But what if they don’t turn on as expected? We tend to take them for granted, and when they don’t function correctly, it can be frustrating.

COMMON CAUSES

Sensitivity Settings
Quality motion detectors usually have settings that will allow you to choose how sensitive they should be to stimuli and how far away we want that stimuli to set off the detector. Be sure these settings are still accurate.

Time Setting
That same motion detector will probably also have the option of choosing how long the light can stay on. Make sure to check that the time duration is what you think it is. It may have accidentally been lengthened.

Reset
Just like our cable TV box and our computers … when in doubt, reset. After you’ve checked the settings above, cut the power to the motion detector completely for at least 10 seconds. Restore power and then see if the lights are now working correctly. Sometimes the simplest solution can be the correct one.

How Many Outlets can be on a 20 Amp Circuit?

The question you probably meant to ask is how many things can be plugged into and used on a 20 Amp Circuit. The typical home has countless outlets for convenience, most of which are not used at any given time.

The National Electrical Code requires that the circuit breakers in our home warn us when more than 80% of the acceptable power usage in any given circuit be used by “tripping” the circuit breaker. You can read more about circuit breakers here.

Using only 80% of our 20 amp circuit gives us 16 amps to safely work with. Those 16 watts give us at most 1920 watts on a typical 120 volt circuit. These numbers are based on safe usage. Who wants to worry about their circuit breaker tripping by exceeding that?

So you are probably still wondering how many things can be run on a single circuit? That is going to depend on the types of things you are plugging in. A typical electrical heater may require 1500 watts when in use, while lights and electronics have very small usage. A safe bet would be to allocate 1.5 amps per item such as these on your circuit.

Common sense should tell you that running appliances and power hungry devices should be delegated to separate circuits. But remember, just because they are plugged into separate outlets, does not mean they are not all sharing the same circuit.
