Line Switch Adapter
« on: February 22, 2018, 10:52:42 PM »
Sarge had a great suggestion recently

http://www.rvforum.net/SMF_forum/index.php/topic,111792.0.html

where he made a dogbone to allow his 50A cord to make L1-->L2 and L2-->L1.

This got my slow brain cranking...  Is it true that many campgrounds are wired so all 20A and 30A plugs draw from L1, while 50A draws from both L1 and L2?  It seems this would cause habitually heavy loads on L1.  On my camper, L1 carries both A/C units, converter, and all 120V receptacles while L2 carries electric fireplace, W/D (not installed), microwave and water heater - a MUCH lighter load.  Is this loading typical??

Would it be worthwhile to simply flip the Black and Red wires in the EMS so MY camper has A/C, etc on L2?  This essentially makes SargeW's adapter the default wiring.

It's not a dumb question if you do not know the answer.

Interesting thought. The advantage though of Sarge’s solution is you can switch to L2 as needed

Just a quick though without really thinking things through, if you switch the wires, then have to plug into a 30 amp site, you've lost your power to the circuits you need the most.

Nope... The 30 amp adapter feeds the single 30 amp 120 hot to both L1 and L2 on the RV end.

6x6x4 utility box, DPDT switch rated for 110V/50A, 50A plug, 30A socket, and cables.

Make a 50->30 adapter that can swap L1 and L2 with the flip of a switch.

It seems the way that your rig is wired Gordon that you may benefit from moving one of the A/C units to L2 in your rig. Since you don't have the washer/dryer option, your L2 is running pretty light. Then if you did employ a switcher, you would always be able to run at least one A/C, and maybe both if you balanced out the load a bit more. 

Gary indicated that most properly wired RV parks would alternate the hot leads every other post. In an older park, or one wired by a not too sharp electrician, that may not be the case.
