Another use of breakers within..........
There's been a number of other discussions about using another breaker for the water heater when you want to utilize the electical heating element to heat water.
Forest River puts the switch for using propane to heat water in easy reach on the control panel inside the motorhome. You would typically use this when "boondocking" and not connected to electrity for your hot water needs.
The switch for using electricity to heat water is located in the outside access panel. This can be seen as being inconvenient for some to have to go outside to activate, as opposed to being located indoors. Also, if anyone was to activate this switch from the outside, and there was no water in your hot water tank for whatever reason, you could burn out the heating element costing $$$$. By leaving the outdoor switch in the "ON" position, you can control the electrical activation of the water heater by using the breaker in the electrical panel. This is a "poor man's way" to substitute for an ON/OFF switch inside the motorhome.
