Questions tagged [electrical-panel]

For questions about panelboards (also known as "electrical panels", "circuit breaker panels", "fuse boxes", "distribution boards", "consumer units", or "load centers"). Questions about individual overcurrent protection devices should use [circuit-breaker].

A panelboard, sometimes called an "electrical panel", "circuit breaker panel", "fuse box", "distribution board", "consumer unit", or "load center", is a busbar or mounting assembly and accompanying dead front enclosure, designed to house overcurrent protection devices (fuses/fuseholders, circuit breakers) and/or circuit disconnecting means (fuseholder disconnects, circuit breakers, snap switches). Other forms of circuit protection (ground fault/residual current, arc fault, and central surge/spike) may be integrated into panelboards as well.

The individual protection devices (fuses and/or circuit breakers) found in a panelboard are discussed in .

No main breaker?

Why don't I have a main breaker? At least I don't see one. Our home was built in 2019. I'm wanting to swap the bottom breaker for a 60A and use 6 gauge wire.

Feeding my 200A, 240v panel with a 120v 4K watt generator

After a recent blizzard, I realized how SOL I'd be if I lost power, and purchased a 4500 watt, 120v inverter generator (3500 running watts). One of my requirements for a generator was "mobile" so I could lift it into the back of my SUV and take it…

Can I run wiring into the right side of my panel, but wire to a breaker on the left side?

I'm adding a circuit in my basement. The wires run to the right of my panel, but I'm out of slots on the right side of my panel. Can I tap into the box on the right, and run the hot wire to a breaker on the left? Or do I need to run the cable around…

Could the MAIN breaker be moved from top left (current place) to lower right side of this panel?

Is it possible (and no I'm not doing it myself), to move the main breaker from top left, down to lower right side of this panel, to shorten the wires and clean it up a bit inside? I'm sure it's a stupid question, but I was curious. Thank you.

Joining two wires into a single breaker

I need to combine two wires with very light room lighting loads into one breaker in the panel to free up one breaker for another use. How best to combine the two wires and insert only one into the breaker (since the two can't fit)?

My Eaton CHSPT2ULTRA is connected to the last breaker (bottom right) in my panel. It seems like it should be the first breaker (upper left) so that it would be in between the main and the rest if the circuit breakers. Is my current installation…
