Hi all,
Since 2015 when I began building it, the trailer’s interior 12V DC and 120V AC from the inverter were floating. In other words, they were not grounded to the steel trailer frame at all and there was no connection to the vehicle wiring.
Now that I’ve installed a Propex heater, the Propex is necessarily grounded to the trailer frame through the copper propane line and propane tank bolted to the frame. (I checked and there is continuity.) That means the rest of the electrical system must be grounded to the frame through the Propex via its 16 gauge - negative wire.
Is it critical to install a ground strap now at the inverter, so that the electrical system is properly grounded to the frame? What are the pros and cons of not doing this?
Thanks!
