Service Panel Repair #3

Here is the installed diverter valve and new plumbing. The one thing I forgot to take a picture of is the installed heater cable wrapping around the plumbing. Darn! I did wrap it around the new diverter valve twice, snaked it around and using cable zip ties attached it to all the plumbing then I used insulating aluminum foil tape to wrap it all up. Then stuffed more pink insulation on top of all that.

Here I have an old 140 Watt Power Inverter wired into the outside light for the service panel. There is a use for those Modified Sine Wave Inverters. When the switch is on at the outside service panel light, there is 12 volt DC power at the inverter providing the 120 volt AC to the heat cable. I put a little rocker switch on the light itself to switch it off so there is no light shinning from the panel causing some people to get concerned. The heat cable is 42 watts so there is plenty of power for the heater cable keeping things well above freezing behind the service panel. I turn on the switch from inside the RV for the driver side outside light to power up the inverter and the heater cable. The 12 volt demand is under 5 amps so that is very good, especially since I replaced the 1141 automotive lamp with a LED Replacement Lamp. I wired into the 12 volts for a reason. If I am "Dry Camping" away from Shore Power I can still keep my service panel warm and 5 amps off the cabin batteries can more than run all night.

In the images above I have the automatic thermostat of the heater cable flat against the brass elbow fitting on the left side of the diverter valve behind the service panel. The specifications say that when the object the thermostat is fixed against drops to 35 degrees the heating strip comes on and when the temperature reaches 45 degrees it automatically turns off. The digital thermometer is actually sort of backwards. Meaning, the remote sensor (outdoor temperature on the display) is fixed to the outdoor shower fixture so to read what the temperature is in the service panel area with the service panel door closed and is reading a nice 43 degrees. The "Indoor" temperature of the digital display of 34 degrees is actually the outdoor air temperature in the driveway where my rig is sitting. I did have a 24 degree night last week and the service panel area remained above 40 degrees. Happy Camper!

Now, to install the Heater Pads on the holding tanks.
