RV Electrical Hookup Basics for Monthly Sites

Answers: How does electricity work at a monthly RV site, and how do I avoid tripping breakers? · Updated August 2026

Shore power is straightforward once you know your service size and your biggest loads. It becomes confusing when people guess.

Quick answer

Know whether your rig is 30 amp or 50 amp, always use a surge protector with voltage monitoring, run your heaviest appliances one at a time on 30 amp service, and expect sub-metered electric to be billed separately from your site rate.

30 amp versus 50 amp

A 30-amp rig has one 120-volt leg. A 50-amp rig has two, which is roughly three and a half times the capacity, not 'a bit more.' If you run two air conditioners, you want 50 amp service.

Managing load on 30 amp

Air conditioner is the dominant load — plan around it.
Electric water heater, microwave, and space heater each take a large share.
Run the microwave or the heater, not both plus the AC.
Switch the water heater to propane on hot days to free capacity.

Protect the rig

A surge protector that monitors high and low voltage is the single best electrical purchase for a long-term site. Low voltage during a hot afternoon damages compressors more often than surges do.

Sub-metered electric

At Journey's, the monthly site rate starts at $500 and electric is sub-metered, so you pay for what you actually use. That is why AC service and thermostat habits show up directly on your bill.

Frequently asked questions

Can a 50-amp RV run on a 30-amp pedestal?

Yes with the proper adapter, but you must manage load — typically one air conditioner at a time.

Why does my voltage drop in the afternoon?

Peak summer demand plus long or undersized cords. A monitoring surge protector will disconnect before low voltage damages appliances.

Follow your manufacturer first. This guide is general information from a long-term RV park, not a substitute for the instructions that came with your RV, appliances, roof material, tires, or propane system. Those documents take priority. Use a qualified RV technician or licensed trade for propane, 120-volt electrical, refrigerant, structural, and suspension work.
