Yeah, that seems to be against conventional wisdom. When camping one might think that hot dogs and marshmallows on a stick over a campfire would be the normal mode of cooking ....

They make them over the propane grille these days.

For lots of people these days. Being in a 40' plus RV and not having 3 bathrooms is roughing it.

I belive the neutral is bonded to ground at the panel. Each camper is on one breaker (120v) there is only one leg available to each camper. I don't see how you could get 240v when there is only 120v at each site. if the neutral or the hot leg where to open it would result in no power. Also if the open neutral were to cause a problem it would effect both legs. all campers that come from that panel. A loose neutral or leg or bad connection would cause voltage spikes, which is damaging. What do you think?

If the neutral is loose in the panel box. You end up with 240 at the 120 volt receps.
The neutral becomes a load/voltage carrying line in that case.

Question

Solve this one (takes some thought).


I am still at a loss. Each camper is plugged into a 30 amp 120v reseptal . The reseptcal has 3 wires. 2 wires, the neutral and the ground (bare copper wire) are at the same electrical potential since they are tied together. If either one of these wires comes loose power would not be interupted since they are basically 2 wires in parrell. If the neutral is loose the current would flow through the ground. I know this is not proper but the circuit would not be broken. If they both came loose which which is possible since they are tied together at the same point in the panel you would have 1 wire that is connected to one leg of 120v. I don't see how you could have 240v with just one wire with no return path. please help me understand.

That is totally wrong. With a 120 volt device and/or receptacle the current does NOT flow through the neuatral and the equipment ground if one of them is disconnected. The only time current flows in an equipment ground is when there is a fault to the ground.

The neutral and ground are not tied to the same point in the camper.
So the ground won't carry anything if the neutral comes loose in the main panel.
The ground wire is also not sized to carry the load. It is usually the next smaller gauge wire.

If the neutral comes loose in the main(as in the screw is loose or corroded, so that it can't travel to the ground either). The voltage is restricted from returning to the source. It will seek its own path. That path is back through the neutral of the other camper lines. And it will use the opposite hot leg, and give you a 240 volt service through the 120 volt circuits.
