30 amp extension cord

Be sure to occasionally check the plugs for heat. If you feel one getting hot, shut it down. Have had the plug ends build up resistance and burn the terminals under load.

Not your typical contact cleaner... to the rescue!

I installed my SSP-30XL inside my power bay out of the weather. The outlet goes to the shore power cord. Also I will not forget it at the pedestal. My Samlex EVO-2212 Inverter/Charger has an Electrical Management System for low & high voltage like a UPS. The EVO-2212 only needed a 30 amp circuit breaker protection from shore power. I used my old generator outlet for the SSP-30XL.

Also it is a portable power tester that I can test my campground pedestal with.

How much power are you going to be drawing at home? Just enough for the converter or running an AC unit or maybe even more up to 30 amps?

More connections in the form of the plugs and connectors on extension cords can potentially lead to overheating. Make sure you keep plug blades clean and shiny with a little sandpaper. Also do no plug in while power is live otherwise the plug blades and contact surfaces inside a receptacle and connector can get pitted and dirty and lead to overheating. As mentioned above, check the cord's plug & connector connection periodically to make sure it's not overheating. Same at the recept. in your home's pedestal.

For those with a detachable cord, you can use a 2nd twist lock type cord and a generator adapter to make an extension cord. We have a spare (30 amp) detachable cord that we keep in case one gets stolen or damaged. Have used it a couple of times along with a generator adapter when we couldn't quite reach a pedestal. Can also be used for putting an autoformer under your RV instead of at a pedestal.

FWIW, the NEC doesn't require a max. voltage drop in a circuit, it only "recommends" a max. of 3% in a branch circuit and 5% total overall for branch circuit + feeder. See here: http://https://www.mikeholt.com/tech...s-part-one.phpNote the reference to RV Parks which recommends a max. overall voltage drop of 5%. 5% as in 114 volts at a pedestal?? Sorry, but hahaha.
