emergency generator power
 
I have a generator with a 30 amp twist lock connection, i plan to use that to feed a power inlet box rated at 30 amps on the out side of my home and from that run 10-2 to a inside outlet for use during a power outage, i am not hooking anything up to my panel. Question is do i need to use a 30 amp twist lock outlet or can i use a standard one on the inside. The only loads will be fridge,tv,a light or two and a fan.

30 amp circuit can not have 15 or 20 amp receptacles on it. You will need a small panel dedicated to the generator with 15 or 20 amp breakers in it.

You need a 10-3 w ground .

just so i under stand, From the power inlet box i use 10-3 to a small panel with a 30amp main breaker and then use 15 or 20 amp circuits in that panel to feed what i want. And again no connections to the main panel will be made.

:eek: I'll assume that's an expression....but I've never heard it before. "In over your head" yes, but not under.

I did the same thing but remember even with that accomplishment we still only know 1% of what there is to know, so we shouldnt get cocky:thumbup:

Is it that you don't want to connect to the main panel? There are small generator panels with the plugs installed that could allow you to use 6 to 10 breakers...depending on the size of the panel. Interlock kits work well, but with just a 30 amp connection you will be limited anyway to what you can run.

Running the generator feed to a small indoor mounted breaker panel or portable breaker panel inside, completely separate from the main electrical system, is a reasonable way to go. It does require running extension cords, preferably heavy duty orange ones, from the small panel to the various appliances and equipment that will use the generator power.

The separate small panel avoids one technicality for which I openly advocate not striving to conform with the National Electric Code. Ground and neutral are supposed to be bonded together in one and only place in the building. I strongly suggest not modifying a generator in any way not sanctioned by its instructions. This may mean keeping neutral and ground bonded at the generator. And I strongly suggest not revamping the panel to have neutral and ground separated for the sole purpose of accommodating the generator (too big a project). Ergo in many situations neutral and ground remain bonded in both places with the homeowner usually not knowing about it or thinking about it. IMHO no hazard is created. (When the generator is unplugged and put away after utility power is restored, the problem of neutral and ground bonded in two places disappears.)

Yes, I sell them a lot.

The Interlock kits from interlockkits.com work fine, but they are expensive and they may not pass inspection in some places. Here in NJ I have had a problem with them a few times, and the word from the DCA is that they are not allowed since they are not listed for use with the panel.

So your best bet is to look for an Interlock kit from the manufacturer, it will cost much less ($40-80 instead of $150 from interlockkit.com) and it will be guaranteed to pass inspection.

As for the first post, if that is all you want to do, just use a good quality typical extension cord with a good 3-way adapater instead. No need to use the twistlock receptacle if you don't want to have it backfeed into your house and you'll only be running: "a fridge,tv,a light or two and a fan".
