Loss of power when I remove item from the outlet

Defective receptacle. Kill it with fire, before it kills you with fire. And if it has backstab connections (wires jabbed in back holes that auto-grab them) this is a good time to get rid of em. ...

When to change Cutler-Hammer electrical panel and breakers?

Not in your lifetime. Nah, it's cool. Eaton has owned Cutler Hammer since 1978. Alien breakers require immediate attention! BRLAFGF115 and BRLAFGF120 are fine. This looks like a Cutler Hammer "BR" ...

3 different units, you haven't used AFCIs before, and any appliance does it, but it does not trip when nothing's plugged in: Did you neglect to connect the circuit's Neutral wire to the matching ...

Loss of power when I remove item from the outlet

Chances are about 90% that you have a loose connection in the outlet. If I had to guess, I'd say it is a "stab-in" wire connection on the back of the outlet (as opposed to the wire attaching with a ...

Is it possible to tell from labels if the breakers are AFCI / GFCI in the main panel?

First, none of you current breakers are GFCI or AFCI. If they were, they would have a "Test" button. Second, you will not be able to fit enough AFCI/GFCI breakers in your panel, even if the ...

Ground Fault Circuit Interrupter vs AFCI

What can happen... If you look closely at the way many AFCIs behave, they will trip on a gross ground fault. This is no accident; instead, they rely on this behavior to catch arcs-to-ground ...

Do AFCI and GFCI protect against cheap equipment and bad wiring?

Do AFCI and GFCI protect against cheap equipment? Not really. A GFCI will limit a shock and an AFCI will limit arcing. There are many other things that can happen with non listed equipment. I ...

When to change Cutler-Hammer electrical panel and breakers?

Panels normally get replaced because more breakers are needed than are available in the existing panel or the total load requirements exceed the panel rating. Panels can also be replaced because the ...

Is there a problem with using a dual function breaker when a CAFCI would suffice?

There's no downside to over-protecting a circuit beyond cost. So having GFCI on a circuit that isn't required to have it isn't an issue. You're more likely to have an arc fault on a lighting circuit ...

The AFCI wire needs to connect to the neutral bus. Put it on the other side, or add on to the length of the wire with a wirenut.
