Hello, First, you need to determine if you are installing a 220 or 110 vac circuit breaker. The 220 is a "double pole" and will have (on the underside) 2 tabs for each 110 phase on your breaker box. It will also usually have a double switch tied together. A single or 110 breaker will just mount to one of the "hot bars" on the breaker box. Again, look at the underside of the breaker. Just remember you need 2 wires (usually a black and a red) for 220 and only one wire (usually black) for a 110 single. The neutral shouls tie to the neutral bar on the box (where all the white wires are connectoed to)

Of course, use extreme caution and insulating gloves when working on a circuit breaker.

Hope this helps and good luck with it. Gary

200 amp


I am pretty sure you would have to order that breaker to get it. if its 200 amp panel it will hold 200 amps. why do you think u would have to derate it for the solar panels. they do not create any electric load as I would think they would actually feed power into the panel and feed it back to the power grid. that would in itself lighten the load on the 200 amp main. I am going to sign up for the mobile app thing. as soon as I read up on it and will be able to discuss this more as u wish and offer assistance if need be.


have a great day and good luck

Using 4 individual breakers tied together with bar accross switches, what size individual breakers will I need to use to use for a 200 amp breaker


50 amps for each breaker?
What are you doing?

Something sounds wrong with your question, and I see a code violation in the making.
Add a comment March 2013 and give more detail about what you are connecting to 4 breakers.
I am concerned about fire hazard.

I have a new furnace and the breaker keeps tripping (20/30). It is a bryant westinghouse box. I think 200 amphes


1) You got a FIRE truck coming.

2) Wire is too small.
Problem is NOT circuit breaker.

3) Both 240Volt appliances on same breaker is a hazard, especially if space available in 200 amp service panel for more breakers.

4) Usually each 240V appliance has separate breaker.

5) Circuit breaker trips because of High heat on the wire.
If wire gets hot, it will start a fire inside the wall.

Electric code requires wire-size match breaker-size.

6) If you put larger amp breaker on same wire that is getting hot, then wire will get hotter.
Result: FIRE truck middle of night with folks jumping out window in glass-cut bare run across yard.

7) Each appliance has volts and watt rating on label.
EVERY appliance has label.

8) For example stove might be rated 8000 watts and 240Volt.
8000 watts divided by 240 volts = 33.3 amps
Stove would require 40 amp breaker and 8 gauge wire.

9) How to figure it out:
http://waterheatertimer.org/Color-codewire.html
http://waterheatertimer.org/How-to-install-a-subpanel.html

10) Do same calculation for new furnace.
12000 watt furnace divided by 240 volts = 50 amps.
Use 60 amp breaker and 6 gauge wire.

11) Summary: fixya wants you to be safe, and buy stuff showing in the ads.
Use a bigger breaker ONLY when bigger wire is also installed.
Call furnace installer, the installer should know to check safe wiring before installing.

Wiring diagram for three phase power with two 200 amp service boxes inside building


This work requires a license (or qualified person) everywhere that the National Electrical Code is enforced.

If you're asking how to wire a single phase 200 amp panel from a larger, 3 phase panel of the same voltage - ONE way is to install a 2 pole - 200 amp breaker into the 3 phase panel. Provide 4 correctly sized conductors with the correct insulation in a cable or conduit between the 3 phase panel and the 200 amp single phase panel. Two of these conductors should be black and red (for 120/208 volt system) and connect to the 2 pole - 200 amp circuit breaker terminals, the third should be white and connected to the neutral bus bar. The forth should be green and is connected to the neutral bus bar as well but *only if* it is "service equipment" If it is a "main or sub panel", the green wire should be connected to the ground bus bar. The other end of the conductors should be terminated in a "main lug only" 200 amp panel. The back and red connect to "line 1" and "line 2" bus lugs, the white to the neutral bus bar that is NOT electrically connected to the panel enclosure (do not install the screw or strap between the bar and enclosure). The green must be connected by installing a separate bar that is securely fastened both mechanically and electrically to the enclosure for ground connections.

There is a great deal going on here - and plenty of variables that can change how to do this work, safely and correctly. This is an example of just ONE of many different ways to do the work for a particular installation. There is no one way that works for all situations. If your situation does not support this method - you will have an unsafe installation and subject the building and people in it to a dangerous fire / safety hazard.

Please, consult a licensed electrician before attempting this work.

Just installing the 200 amp panel and would like to know where the bare copper ground is supposed to hook up? Is it on the opposite end of the neutral bus?


All neutrals and all ground wires connect to the neutral bus. Where you connect them on that bus is simply a matter of being tidy and leaving room for future work. Of course your physical ground (the one going to the copper rod pounded into the earth) must be connected to this bar too.

I am trying to install a 100 amp breaker into a Homeline 200 amp load center. Breaker flips every time main breaker is turned on.


I'm assuming since it's a Homeline panel you're using a HOM2100 breaker. If it stripping then you must have a short circuit in your 100A circuit, or the breaker is defective. Disconnect your load from the breaker, and turn main on. Be sure you have the correct load conductors connected to the breakers. Typically red and black on the breaker, white on neutral bar. Bare to ground bar

GE THQB 1 pole 20 Oily liquid appears to be seeping from multiple breakers, different panels but not all breakers. Breakers installed 1992. Any thoughts?


Hi,
There is no liquid in those breakers to seep out... my thought would be that some one used an anti oxidate compound on the wires when they installed them and that is running a bit as the breakers and wires heat and cool....
I would just check the wire connection for tightness and as long as the connections are tight I would not worry about it...

30 amp 2 pole GE GFCI breaker pops on hot tub after hrs of use


I have seen circuit breakers trip at a lower amperage. It seems that they are weak. Generally circuit breakers run with 80% load with no problem, in your case 24 amps. I would replace the circuit breaker.

Bought wrong panel


no, not to code plus the expense would not justify , you can purchase the 200 amp panel with the main already installed cheaper than purchasing the 200 amp breaker in most cases and still meet the code check on a panel package called a home owners kit ge makes one square d , makes one either good quality , you get the 200 amp panel, several breakers such as 20 amp 50 amp 30 amp by far the best route for you
