Pulling more than 50 amps ?

On an RV that has zero 240 volt appliances is there a reason to have the tied 50 amp breaker instead of two separate 50 amp breakers?

100 amps available....50 amps per leg x 2 legs...so answer is yes

Agreed! I routinely use in the 60+ amp range when camping during the winter and using the electric fireplace and 3 other portable electric heaters for warmth plus the electric water heater. The 3 other heaters are strategically plugged in such that neither 50 amp leg is maxed out. I've been doing this for several winters now.

If the loads were perfectly balanced and wired as 120/240, there would be 0 amperage on the neutral.
If the receptacle was wired with the same 120 volt leg on both, there would be 100 amps on the neutral.

Finally, a good explanation

Uh, the CG electrician didn't say you cannot draw more than 50 amps on a 50 amp plug. According to the OP:

"Our park electrician says that some of the big rigs with 3 ACs and electric everything can sometimes draw more than 50A from a 50A pedestal."

What am I missing?

My thoughts also. I really got confused by the name calling over what seemed such a simple statement.

My simplistic mind saw no confusion on the electrician’s statement. I read it as him implying that the “big rig” could draw more than 50 amps from one leg of the 50 amp service and trip that breaker.

I read this again. It is worded POORLY. The answer is, YES, THEY CAN DRAW MORE THAN 50 AMPS. But, the 50 amp pedestal handles a TOTAL of 100 amps. Doug

Which wire has the 100 amps on it Doug?

It is 50 amps on L1 and 50 amps on L2. Voila, 100 amps used in the RV. Sheesh, I thought you, of all people, knew this wa8yxm.

Ok, but wouldn’t Neutral wire have to be rated at 100A or higher?

How about we deem this one CLOSED!!!

AS stated, The POST was poorly worded.

When you first replied to my question, it took you 4 posts in the space of 15 minutes to get the gist of what I was asking. Others did not seem to have that problem, and your oft-repeated "poorly worded" comment appears to be a weak cover for just not getting it.

I think it's just poor reading comprehension on your part, Doug.
