![]() ![]() The wiring from an inlet box to a transfer switch is permanent building wiring, so cordage such as the SOOW you propose is completely the wrong stuff for the job. This is permanent wiring, so you need to use cable (or individual wires in conduit), not cordage This wire will run along a wall from the panel location outside to the back of the house to where the generator will be placed for security and safety.Īny help and insight will be greatly appreciated. I have basic knowledge but this is something not to mess around with and will be going with an electrician, I just want to have all items available to reduce the chance of being overcharged (tends to happen in my area even with the pros around here). The inlet box itself is a 4 prong, NEMA L14-30p 30 amp since the generator itself is also 4 prong inlet. If neither are applicable, which would be best to use that is 4 AWG? The issue I am running into is whether to use 4/4 SOOW cable or 4/3 SOOW cable to do the run. ![]() I would rather use thicker wire than thinner wire, better safe than sorry.The distance it's going to cover is about 60 feet from the transfer panel to the inlet box.It will currently be a 30 amp system (eventually 60 amp).I want to set up wiring for 4 gauge wire to cover my bases for future upgrade.The generator itself is a Westinghouse 7500 model that explicitly states that the neutral bonding has to be undone in order to use it with a transfer panel (due to having GFCI outlets in house).I am attempting to gather the supplies needed to setup a secondary panel for a backup generator.
