RV park pedistel voltage

[Lurker52]

When at a park and testing the pedistel 30 and 50 amp outlets what should be the voltage? Is the 30 amp 120 volts on one leg only with the others being the nuetral and the ground. Is the pedistal only running a 120 volts or is it 240? What shoud the voltage be for a 50amp? I would like to know what is correct.

Thanks

Get a Progressive 50 amp surge suppressor. It will tell you exactly what the voltage is on each leg and the amps being drawn on each leg. Also, good surge protection for the coach.

Actual voltage will vary depending on demand as well as how well the system was designed, distance from the transformer, etc. It is supposed to be 120.

I suspect you'll get readings around 117, maybe 115 on a warm day with several campers using their air conditioning units. My electrical system won't accept 107 volts, as I found out once, so I used a battery charger to keep my batteries charged up.

Normal voltage can range from about 112 to 128 volts Ac. Emergency can go as low as 108 and high as 132. Damage to electronics can start above 132 volts.

Good previous post on power. RV parks are all over the map on voltage. I pulled into a small very well kept RV park. Hooked up to 50 amps & blew the breaker with 1 A/C on. When they came out to change the breaker I had a chance to look inside the box. Looked like it was #12 wire. The whole box was hot pulling 18 amps. I have gone into other parks and pulled close to 50 amps with no problems.

This is a typical RV camp ground pedestal wiring diagram showing the 50A and 30A RV receptacles and the associated AC Voltages..



These are AC VOLTAGE measurement diagrams for the RV 50A and RV 15A/20A/30A pin outs

15,20 and 30 amp are 120 VAC with one hot, one neutral and a ground.

50 amp has TWO hots, a neutral and a ground. Measuring from hot to hot (outer straight to outer straight)= 240 VAC
