Electrical From Scratch

The professionals will keep you alive and healthy.

Is the insulation you intend to spray in approved for human habitat? I would hate to hear 10 yrs down the road you have tumors or a respiratory ailment from it.

China drywall comes to mind.

If everybody in the world left to some professional to do then nobody would learn anything and everyone would be broke!

Very good explanation and very simple.

Thanks a bunch. I even have this stuff lying around from left overs. It might be better to use a short piece of BX.

Thanks again

I do have a sense of adventure but I'm also a EE.
Go back and read your first question. Very basic electrical questions. They were on my 1st test in EL101.

My point was that if you don't know the answers you should leave this to someone who does.

With that said: the 60A convertor is 60A DC @ 12V. To convert that to input it would be 120V/12V is a factor of 10 therefore 60A/10 would be 6A feeding the convertor at 120VAC. Ignoring any power factor and consider an efficiency of 80% it might draw 7.2A. I would still use 12AWG wire.

The campsite pedestal usually have 20A/30A/50A service. Go 30A for possible future expansion. You can adapt that down to 20A with a $4 adapter.

I was asking what wire to used to feed the panel on a RV as I have never installed a panel to feed a converter or a RV before. I dont know what amperage is supplied at campgrounds or what a converter draws.

I've completly wired my house and passed code on the first attempt. I wasn't asking what wire to use I was simply asking if 4 plugs in a RV was enough. it seem like plenty to me. I don't see any need for a 20amp circuit. I've never owned a camper or camping belongings. Will I need my MIG welder while camping to justify a 20amp breaker. Probably not. Lol but may come in handy.

If you use #14 wire for a branch circuit, then a 15amp breaker is the largest you can use. For #12 wire, 20amp.
The proper wire size for the converter is determined by it's rated amp draw. What is the rated amp draw of your converter? The AC draw, not the DC amp capability.

I thought these converters were all the same input and draw to run them. this one is 1000watts at 60Hz on 105-130v

Be careful.

Bahh you have no sense of adventure!

I assume you are going to use 30A service. That would be 10AWG at a minimum. If it's over 30' consider 8AWG.

The convertor should be serviced with 12AWG.

Consider using 14/2 with gnd Armorflex and associated components for your service runs.
