8289WS 110 Wiring

I have a Progressive Industries EMS-HW50C Surge Protector, and the last time we were out I noticed that we were pulling most of our load on one leg of the 50A service.

I had some time today to analyze how the RV was wired in detail, and was surprised to find that EVERY 110 receptacle in the RV is on the same leg. This is how the RV is currently wired:

Leg 1

Breaker #1 (15A) ALL receptacles from the kitchen to the back of the RV, including the TV.

Breaker #2 (15A) Refrigerator, ALL receptacles from the bathroom forward, including the TV receptacle in the bedroom and the receptacle located in the understorage.

Breaker #3 (15A) Microwave

Breaker #4 (20A) Living Room Air Conditioner

Leg 2

Breaker #5 (15A) Water Heater

Breaker #6 (15A) Bedroom Air Conditoiner

Breaker #7 (20A) Converter

So for us, in moderate weather where the Bedroom A/C is not being used, with the exception of the Water Heater and Converter, everything is operating off one leg of the input power.

Besides being inefficient (larger neutral current than a more balanced load would cause) it has a tendency to pull down the voltage on Leg 1.

MY PLAN

I'm going to install another Breaker on Leg 2 (there's room in the Power Distribution Panel for another Breaker) and move the load on Breaker #1 to Leg 2. This will transfer the TV and any appliances used in the kitchen (coffee pot always on) to Leg 2, providing a more balanced load on both legs.

OBTW. I found that with all breakers turned off, the ceiling fan in the Living Room was still operational. Didn't know that it is a 12V ceiling fan, but I do now.
