Can I pull the Neutral from a nearby outlet for a Sub Panel?

both the neutral and the ground have to run back to the main breaker panel. the ground must be tied to the main ground that tied to the ground rod. the sub panel must have the bonding strip removed and no second ground rod can be used. check your local codes or have a licensed electrician install the sub panel.

You can end up with some very serious problems by not wiring a sub panel properly.If you have a twenty and thirty ckt there will be a difference of 10 amps.If the sub panel is bonded to the neutral from the main panel, the sub panel box can be electrically live and be a very dangerous shock hazard, even if the sub is just a 120 volt system and u r pulling say 25 amps with the neutral tied to the sub panel box then yes the sub box can/will be live to ground. That is why the code says the neutral MUST be insulated/isolated from the ground or metal enclosure of the sub panel the sub panel box

Wow, so let me get this straight. You want to run a 100 amp sub panel with a neutral wire that even if to code would only be a 12 ga. wire which is good for 20 amps max. The answer is an emphatic NO!!! Not only is it not to code but it is flat dangerous. Neutral wires are an insulated grounded conducter and carry current under normal use. the neutral wires in your home are only protected by the circuit that the live wire it shares is protected by. In this case the neutral in your garage outlet goes back to the first panel to the neutral bar. That means that neutral could be asked to carry the entire neutral load of your sub panel which could be as much as 80 amps. A #12 ga wire carrying 80 amps with a 100 amp protection will be like a toaster element running through your walls! The potential for loss of life is huge and if that doesn't happen then the inevitable fire will and fire insurance won't even help that disaster as that problem would be found and your claim denied! If you are seriously asking this question you need to turn this job over to a licensed electrician.

You are putting a 100 Amp subpanel in the garage. This is a main lug load center, not a main breaker load center.

You must run a 4 conducter line back to the main panel. The "hots" are red and black, the white is neutral and connected to main panel neutral bus. The green is ground and connected to main panel ground bus (which is also the neutral bus).

In the main lug load center, you must separate the neutral bus from ground bus if it is not already separated (some load centers can be either main breaker or main lug and altered in the field to meet local needs).

Failure to wire it properly is a code violation and a major risk. Further if there is an electric fire that arises later, and fire inspectors see improper wiring, the insurance company may deny coverage. Electricity is not forgiving so do it properly the first time.

I did not check the wire size for 100 amp service, but I believe you need # 4 which means the cable you need is 4/3 with ground. You are going 200 feet which is a substantial distance so be sure to oversize the wire gauge.

Sounds like you are trying to save more than just the 200 ft of wire. Your installing electrician will tell you that it has to go back to the main line as well as having a ground rod in the ground to attach a secondary ground to the box as well. Hope you have at least a 200 amp service to the supply panel you are running off as well as the proper gage wire to run 200 ft.

man iif i no anytthign bout working at the exxon, i no that it be best if you dont stick a fork into th e nearby outlet cuz you get a shock man. man my afro was stuck up even worse than normal but thats how we roll. RAP ALBUM OUT OCTOBER 20
