How the Breakers in the Electrical Panel Keep Your Home Safe


Welcome to your breaker box. If you’re lucky enough to have an electrician
that has good hand writing and good spelling skills, then you’re doing good. All of the breakers are going to reset to
the middle of the panel like this. You’ve got two types in here, you’ve got
an AFCI, and GFI/AFCI (GFCI/AFCI) breaker, so light blue is the GFI type, and the dark
blue the AFCI type, that stands for Arc Fault Circuit Interrupter. They’re required by code, and they’re
a safety device. You have a cord, a bad cord, could be a fire
hazard. This will trip, so you don’t start a fire. To reset, as with any of these breakers, you
can’t just push them to on, you have to cycle it to off, and then back to on. Now these new style AFCI breakers have some
LED indicators on them that will indicate the type of fault that caused it to trip. One LED, when I reset this you’ll see, one,
that indicates an arc fault. So that’s like a spark, or an arc, or a
bad cord or something like that on an appliance. So that gives you some idea. If you have two LEDs that illuminate, like
this, that indicates it was a fault to ground, or a short to ground. So that gives you some idea of why it tripped. Now to erase or reset the memory on those,
when you push to test you’ll hold that down, switch it to off, and then back to on. That will reset the memory for why it tripped. In the instance of an overload, which is too
much current on the circuit, it will simply just trip, and you will have to reset it and
there will be no LED indications for why it tripped. Now the GFI/AFCI (GFCI/AFCI) breakers, these
are just like a GFI outlet (GFCI outlet), which we have in the house as well. And these are going to be found anywhere where
you have an outlet near water. But you may not have these in the house, you
may only have a GFI breaker in the house, but it’s going to protect just like that,
or you may have a combination of both. So you can look for that, if you don’t have
those in a garage, in a kitchen or in a bathroom, then that means they’re located in your
breaker panel.
