You cannot wire the Therma Heat RV Holding Tank Heater Pad w/ Thermostat # 277-000163 in series but you can wire them together in parallel to add 4 of them to your camper. This means that you will daisy-chain all of the positive (Red) wires together and connect them to the battery on your RV, and you will daisy-chain all of the negative (White) wires together and ground them. You can add wire length as needed # 16-1-1.

You can use the Pollak Universal-Design Rocker Switch # PK34310 between the battery and the pads as a way to turn them on and off. Since the switch is rated for 20 amps and the pads will only be drawing 10.52 amps you will not need a fuse.
