Electrical Service Connections

[greywynd]

Ok, my post, and reading others here has me wondering, what/how many different electrical services are there?

Is there a Chart/picture somewhere that shows the common configurations? I realize that 110V/15 amp, and 110V 30 amp are common for a lot of the older units, now there's getting to be more, larger stuff, what else is out there?

I guess one of the things that I'm trying to figure out is what sort of adapters does one need to carry?

Gray, on my coach which has a 50amp service I have a 50female to 30amp male dogbone adapter, a 30amp 25' cable so I don't have to pull put 50 amp service cable, a 110v 15amp cable with adapter for connection at house. Alot of CG's around here have only 30amp service, down south an west will have 50amp I have found. "007"

So far we haven't had any issues ourselves, I've been watching what is available at the sites that we've been at, the 'standard' is the 110v 15amp and 30amp, but most of the sites we've been to also have had 220 volt outlets. (We only run 110 onours, and 15A handles it without a problem.) the only time we had a problem was this summer, we were camping with friends that have an older trailer, they only had 110volt, 15 amp, and there was no standard outlet on the distribution box. Knowing that our load is always on the light side, and theirs was only for lighting, we ran a cord to their trailer from one of exterior outlets. I was surprised though to find that there was no 110v outlet at the box though, it was right beside the 'parking' spot/picnic table, so I would imagine that people would often use it for a radio or whatever outside.

They also have 50amp to 30amp dogbones if you find only 50amp service, I also pull a popup at times and feed 110 to it from 110 in coach. "007"

So there's a 50 amp 110volt available too? I would have thought that it would be 220volt....I really didn't look at the specs on what was on the larger plugs at the sites...

50 amp receptacles are 120/240 volt and use four wires. The round prong is called equipment ground. This is what would be connected to the frame and skin (if metal) of the RV. Then the flat blade straight opposite from the ground is the neutral. The other two are the hot legs. Measuring voltage from either hot leg to ground or neutral will be 120 volts. If you measured across both hot legs you will read 240 volts. As longg as your unit is only using single pole circuit breakers you are only tapping into one hot leg and therefore using only 120 volts. If (and a few do) have a 240 volt dryer this circuit would use a 2 pole circuit breaker and tap off the two hot legs giving it the needed 240 volts. I recommend the use of the Surge Guard to protect the unit at the service.

The dogbone that addapts 50 aamp to 30 amp only uses one of the cicuits available to the 50 amp service. therefore you are only getting 110 volts.

The surge guard option recommended is a good idea safeguard for protecting the equipment in your unit no matter how you are plugged in to power.
