Hi all. I have a portable generator to power my sump pump in the event of a power outage. Rather than snaking an extension cord that will reach from my driveway to the sump pump in the basement, I am installing a 120v outlet/receptacle next to the existing sump pump outlet and hard wiring it to an "inlet" in the garage that I can hook the generator up to when the need arises. Here's what I need help with. My generator has an L1420R receptacle on it for 120/240V. I have a cord set that fits it. I have a matching flanged L1420 inlet receptacle that I want to put in a box in the garage. My plan is to run the 240 volts using 12/3 wire w/ ground from the garage box down to the basement by the pump. The pump is 120v. Can I use a regular 20amp 120v duplex receptacle down there, seperate the hot side (break out the little tab that connects the 2 outlets together) and then wire the 2 hots seperate ( a red and a black) and run my white neutral to both giving me (2) 120v outlets? Is this sound thinking/safe or am I nuts? What I am trying to accomplish is having 1 outlet available for the sump pump and 1 for a light in the basement when using the generator. Figured I would have more amps available if I used the 240 outlet on the generator rather than a single 120 on it. I also like the twist lock feature so the cord doesn't pop out. The 120v outlets on it do not have that feature. I appreciate any and all input! Thanks.
