Should a Relay be Used With Wagan Power Inverter


I have an OEM switch for my vehicle, but its only rated at 3 amps. Id use it to control a relay to apply/remove power to the inverter. Can you recommend a suitable relay for this?


Expert Reply:

Though I can see why you might think you need a relay, I do not recommend using one with the Wagan Power Inverter with Three AC Receptacles # WC3720.

This inverter has a simple On/Off switch; I assume you want to use a relay to conserve power from your battery but the same thing can be accomplished simply by turning the relay off. Just be sure to use the correctly rated fuse and wire gauge for the length of wire you need (which is included in the installation manual I've linked) to get the best performance from the inverter.
