Question about Cutler Hammer 200A 2POLE CIRCUIT BREAKER

Hooking up generator switch panel

To a cutler/hammer box. Only issue is how do you tell the difference between ground bar and neutral bar. Assuming the much larger guage wires go to the ground bar. Problem is wires that look like ground go to both.

On a residence, the ground bar and the nutural bar may be hooked togethervia a ground screw on the case.    In that case it matters now which side you use for the nutural and which for the grounds. Just make sure to keep all of the whites on the white side and the greens on the green side.

My incoming service has two insulated and one bare wire, i'm not sure where to connect them

the BLACK wire is your hot wire that goes to the breaker, the WHITE wire is your neutral bar connector & yes your bare [brass color] wire is your ground only. always use insulated tools when making any electrical conections. be safe.

Can a 100AMP Culter Hammer Main Breaker Be Upgraded to 150AMP Without Changing the box or wiring?

only if your main wires (ie. line/feeder wires) are larger than a #2 awg wire size. #2 awg size wire is code and the right size wire for 100 amps. So, if you have larger wire coming into your service (eg. #1 THHN or larger) - then you can. Otherwise, you'll have to UP the wire size for the appropriate amperage. I hope this gives you some idea! Good Luck!

Cutler hammer 60 amp non-fusible disconnect... looking for instructions or a diagram to install

You connect the two hot wires from your power source to the two lugs in the. On the other side of the disconnect you connect the two hot wires to the A/C unit to the other two lugs. You tie the neutral wires (white) together and insulate them. You ground the ground wire to the box and run a ground wire to the AC unit.

So, you should have a red, black white and ground wire on the supply side to your disconnect. The red and black are your hots from your main box to the disconnect. They go on one side of the disconnect. The units red and black go ont other side. You connect the neutrals and ground it and you are in business.

Don't guess, because you are fooling with 220 Volts AC which will knock you silly.

I have a cutler hammer circuit breaker box 125 amp. i need to know where to place the ground wire and where to place the common wire...

There should be two metal bars with multiple screws--one should be mounted directly to the metal box (grounds), and the other looks the same, but is mounted with insulators from the box (neutrals). The ground is usually a local ground rod driven near the box to a depth of 8'. A #6 ground wire couples it to the ground bar. The neutral is brought in with the two hot wires (230 volts) from the transformer. One hot wire and neutral gives 115 volts. Hope this helps!

What gauge wire do I need to lead into the BR816L125R load center? it is going to the feed through lugs off my 200 amp service breaker.

Hi .. If the load center is next to the main panel you can use #2 copper or #1aught aluminum. You need to use 4 wires .. two hot, neutral, and ground. And in your load center you will need a 125amp main breaker and you will need to keep the neutral bus separate from the box, do not use the bonding screw. You will then need to install a ground bar to the back of the box for the ground wires connection.
any thoughts, questions.?

How to hook up single pole shunt tip breaker in panel

To be very safe, turn OFF your Main circuit breaker prior to doing this. This IS really important! You asked how to hook up the breaker, so I'm going to assume you already installed this. The first wire that you'll want to land under a screw is your ground (green) wire. This wire should be where all your ground/green wires are. Next, you're going to bring your white (neutral) wire to the neutral bar.  You should see other white wire's terminated (attached under screws) there. Then, bring your colored (ie usually a black or red) wire and attach it to your circuit breaker. Make sure that you are using a #10 guage wire. This wire guage is rated for 30 amps. If you're using a 20 amp circuit breaker, then use a #12 guage wire. And a #14 guage wire for 15 amp circuit breaker. Using these wire guages satisfy all electrical requirements (codes). Now, leave the circuit breaker in the OFF position, and close up your panel. After closing it, then turn ON your Main circuit breaker. If everything is fine, great! Before you turn on your circuit breaker, make sure the switch, device, receptacle (unplugged), is OFF. Then go to your electric panel and turn ON the circuit breaker. If the breaker holds (doesn't trip), then try your switch, device, or receptacle to see if everything works. One last thing to remember is, if you're using a 30 amp circuit breaker, then the device on the other end should only draw up to 24 amps. Meaning, don't put a 30 amp cir. brkr. on a 20 amp recectacle, switch, or device. For a 20 amp cir. brkr., 16 amps is the maximum load you can put on this. I hope this helps you. Just read it through once, and then highlight the main parts of this and you should do fine. Good Luck, and feel free to contact me if you'd like further assistance. - Jim

I have a cutler hammer breaker box & my question is where do the white & ground wires go cuz the bars for them are not the same length one is on the left of the box & the other is on the right

Look at the how the bars are mounted within the box. The neutral wiring (white) goes to the bar that is insulated from the box metal, while the bar that is mounted directly to the box is for circuit ground wiring (bare). Hope this helps!

I have a question

Sounds like the breakers are mis-wired. This is a common mistake with those kind of breakers. The white wire that is permanently attached to the breaker (usually coiled) connects to the neutral bar in the panel. Look closely on the breaker, you will see two terminals. The white (circuit) wire that goes out to load connects ONLY to the neutral terminal _on_ the breaker itself, _not_ to the neutral bar in the panel.

Need a wiring diagram for a cutler hammer 100 amp double throw safetey switch the box came with no manual

Line voltage (source power) goes to the lugs on the top and load (goes to the device) is on the bottom. If it is designed for single-phase power (with a neutral), there should be an isolated block with lugs for neutral, but if it is not, just get an inline lug (available at a hardware store like Home Depot) to connect your neutrals and then insulate it with electrical or rubber insulating tape. Then you will need to bond your grounds (from the source AND to the device) to the can.
