Two circuits in panel inoperative

I just installed a new QOC20U100F panel & the power surges (lights flicker) with the breaker in #7 & #19. When I move the breaker (hot attached) to any other location it works fine. Does this mean the panel is defective? Thanks

    Thank you for the quick response! I'll follow your advice as I'm sure you're right. That was my first thought also & spent a couple hours working back to the panel.

Not likely check the neutrals on those circuits the chance that 7&19 are bad and everthing in between is good is almost impossible. i would check the wires very close and also inspect the neutral buss connections both main connections and circuit connections

Room heater caused 15 amp circuit breaker to go bad. Can we update 15 amp circuit breaker to 20 am (similar to ones next to it)


Probable not, in order for you to install a 20 amp breaker, the wiring must be a #12 gauge cable.Check the power requirement of your room heater. It should be not more than 15 amps. Check and retighten the connections to the heater.
Install a new 15 amps breaker.

My Sylvania - ground fault 15 amp breaker (32740) is tripping with minutes of reseting. It is for 3 washrooms & hallway & is 30 years old .....does or can it loose its life span? What is the cost...


A circuit breaker can go bad, but usually not in the way that you describe. That's not to say that it can't happen, but just not typical. GTE Sylvania breakers were once popular - I installed quite a few GTE / Sylvania electrical panels in homes in the late 80's. You may have trouble finding replacements; do not put an breaker that "fits" into the panel, unless the breaker is designed for use in the panel you have.

The first thing to do is determine the source of the problem. The breaker will trip, but not indicate if it was the result of a heavy electrical load or a ground fault condition. A 15 amp circuit breaker is designed to carry up to 12 amps continuously. The greater the load, the more quickly it will trip. it may carry a 14.5 amp load for several minutes to an hour before tripping, and a 20 amp load may be carried a second or two. GFI breakers are designed to carry 5 thousandths (.005) of an amp (or 5 milliamps) to ground, or the 12+ amps to neutral before they trip.

The way I would attack the problem is to install a new GFI outlet in front of the old wiring, by "inserting it" between the panel and the other plugs and lights, switches, etc on that circuit. The GFI outlet will provide the same GFI protection that the circuit breaker provided at a fraction of the cost.

Turn off the old GFI breaker, and remove it completely. Install a new, standard (non-GFI) single pole 15 amp circuit breaker in its place. Completely remove from the panel the cable that the old GFI breaker fed. Buy a new electrical outlet box (surface or flush mount as desired) that is large enough and deep enough for a GFI plug and 2 cables (if surface mount, use a 4" square deep box and appropriate cover - or if flush mounting use a deep plastic / fiber single gang box). It will be installed in a place close to the panel, but where the old cable will be able to reach inside. Bring the old cable removed from the panel into the new box. Run a new cable that has the same number and size wires from the panel into the new box, too. Connect the circuit neutral and circuit ground to the neutral and ground bars in the panel (they are probably the same bar) and the hot wire to the circuit breaker. make sure that the circuit breaker is OFF. Twist the two ground wires together and combine an 8 inch length of bare or green insulated wire with them in a wirenut.

Next, wire a new GFI plug in the new box. Connect the green wire from the wirenut to the green terminal of the GFI outlet.

Connect the plug's LINE terminals to the neutral and hot wires in the cable that you ran from the panel to the outlet box.

Now, connect the GFI plug's LOAD terminals to the neutral and hot wires in the cable that you removed from the panel and reinstalled into the new outlet box.

Secure the GFI outlet into the box and install the cover. Cover the electrical panel.

Power up and test. if the GFI trips, there's a ground fault in the circuit. If the circuit breaker trips, the circuit is overloaded.

Can i replace the main (100 amp) is a sq d QOC20u100F panel with a 200 amp main--i will up grade meter socket and entrance cable to 200 amps cwalker


First the part number QOC20U100F is a flush mount panel cover. The panel you have is most likely a :QO116M100. No you cannot replace the breaker as the bus in the panel is only rated for 100A. In addition I believe this is a 20CKT panel. If you're gonig to a 200A service you'd probably want more spaces than that. Home Depot and Lowes both carry 200A panels with starter set of breakers at reasonable price. The QO panels are a bit better than the Homeline
Here is a link to manual for their panels. :

First switch off the power at the main breaker or pull the meter from the meter socket. If you flip off the main breaker and it is mounted in the same breaker panel, just be aware that the wires above the breaker are still hot. Connect the white wire to the neutral bar, the green wire to the ground bar, and the black wire to the breaker. Then tilt the breaker to get the front black lug under the bar and push the back of the breaker onto the lug on the bus bar.

Hello: I have an old electrical box with the old style Zinsco beakers. For some reason, the left side of the main 200 amp breaker continues to go out. only one side. the breaker arks right where I screw...


The screw is loose. It is always HOT (has electricity going to it) so be careful. If you feel confident, cover a screwdriver with a few layers of electrical tape and tighten it. Depending on how long it has been arcing, the breaker will need to be replaced. Since the incoming wire will have power to it, have a licensed electrician do the job. He will possibly remove the meter head to cut the power while he does the work.
