How to install a 30-Amp RV Power Outlet with Branch Breakers

Excellent forum for doityourselfers. Thanks

I'm swapping out a 30 Amp RV plug for a 30 Amp RV plug with two 20 amp branch breakers / outlets.

The first RV outlet I installed I used 8 gauge wire with a black white, and copper ground. The 30-Amp RV Power Outlet with Branch Breakers schematic shows a "red" wire too. I have no idea what to do now. Does anyone know what the red wire is used for? The cable I installed does not have a red wire. I assume the green wire in the schematic is ground. Thanks in advance. Please see pics. Jim

That box is designed for 120/240 volt power input. You only have 120 volt power input. One of the breakers will not function unless you run a new cable.

Hi, if the lugs are rated for 2 conductors ( I doubt it) then you could install a jumper between the black and where the red conductor is supposed to be installed.

Thanks to all. See pic please. Could I wire a jumper as depicted in light gray color?

The lugs are not rated for two wires. Use a wirenut and two short jumpers of wire to split the incoming hot wire to both lugs of the panel. A red or blue wirenut can accept 3 #10 wires.

Thanks to all for the support.

Ben, I will pre-wire the panel before installing and post a pic for comments to ensure I have the "split" correct as you described. Thanks again for the assist. Jim

Old Air Handler/Thermostat Wiring Help

J

jakeneedshelp on Jul 30, 2019

Hey all! I've got an old house with radiator heating and an air handler/AC for cooling. Put in new wiring/service recently, and looking to hook up the air handler and A/C to see if they even work. Looks like the air handler was powered with 14/2 (15 amp) is that sufficient/correct? I'm mostly struggling with how to connect a thermostat to the old beast to see if it moves air. I have some 18/5 wire, not sure if I need more- or if it would be smarter to run it with more conductors before drywall goes up... The only label I found on the air handler is a small placard (pictured) I've (hopefully) attached some pictures. If I need to provide more info, please let me know! I'd greatly appreciate any advice/guidance/instructions on how to power and connect a thermostat to this thing! Thank you

Sub Panel Review and Question

S

Installed my sub for generator and everything works fine however I have a few questions. Setup: #4 from 60amp in main to 60 amp in sub. Removed ground screw in sub and connected #6 ground from main ground non bonded to ground bar in sub. Neutral to Neutral. 1. When I kill a breaker and then check my splice in junction above, ground is energized white, black red not. I don't think this is normal, Is this normal? 2. These 3 are MWBC, Had to order 2 pole breaker for the 2 circuits that are using 1 pole, will replace when they come in. Does my setup look ok? Still need to run generator wire and receptacle. Thank you.
