Generator 220v Twistlock - (2) 110v outlets

Good idea on posting to alt.home.repair also. So that outdoor inlet that I linked to is $53. I saw some L14-30 flanged inlets on ebay for $12 plus $4 s&h (http://cgi.ebay.com/ws/eBayISAPI.dll...=110079121868). The trouble I am having is finding a outdoor 3R or better rated box that would accept a flanged inlet. Does anyone have any suggestions here. If I can find such a box for even $20, it would still be a savings over the $53 Gen-Tran. Also, are my wiring assumptions correct? Common neutral and each positive leg to each duplex outlet? Thanks in advance, Chris Speedy Jim wrote: wrote: satellite_chris wrote: I am planning to install a power inlet box on the side of my house to accept an L14-30 connection from my generator's twist lock receptacle L14-30R. Here is the particular outdoor enclosure that I plan to use: http://www.gen-tran.com/eshop/10Expa...ductCode=14302 From there I would run a small piece of conduit from that input box to a new electrical box on the opposite side of the wall in the house. I plan to wire a separate duplex outlet to each leg of the 220 with all the neutrals connected to the common neutral. This set of outlets would obviously be in no way connected to the rest of the house's wiring system and I would use a different color of outlets. Would this be up to code? The whole concept here is to have a convenient way of bringing the generator power in to the house without having to leave any doors or windows open to allow an extension cord in. These 4 outlets would be in a convenient location in the house where I can plug in my critical electrical items. Thanks in advance. Chris I'm not an electrician and don't know whether you idea would be up to code or not. One question I would have is what you are going to do with the ground wire. What you are planning sounds like a heck of a lot of work and it won't be all that useful when you get done. I wonder if there's some way that you could (legally) connect your generator directly to your service entrance box via some sort of inexpensive, manual transfer switch? The gennie absolutely must be grounded (to earth) and the Neutral bonded to Ground. Rather than sticking a pipe in the gound, consider running an equipment ground to the grounding point used by the house service entrance. But your idea to run a conduit into the house for dedicated receptacles sounds good, since it won't in any way be connected to the incoming power line. "inexpensive, manual transfer switch?" They are neither inexpensive nor simple. Done properly means a lot of tricky work. For more opinions on this setup, post over to: alt.home.repair Jim Jim You may be behind the curve here. There is an interlock kit available from at least two major service equipment manufacturers that interlocks the main breaker with a two pole breaker that controls power from the generator. The kit cost around fifty dollars. -- Tom Horne "This alternating current stuff is just a fad. It is much too dangerous for general use." Thomas Alva Edison |

The "kit" may be $50, which gets you some mechanical parts, but that doesn't address the complexity of the wiring that needs to be done and it presumes that OP has the "correct" Main breaker in place. They are a neat idea though and a good solution to the whole house transfer switch problem if one were building from scratch. Jim |

A four wire cable is run to a flanged inlet that is cut into the bottom of any surface mount 4" X 4" X 4" Weather proof box. The black and the red go to the interlocked two pole breaker. The white and the green go to there respective buss bars. About a third of the homes built in the last fifteen years have compatible main breaker panels. -- Tom Horne "This alternating current stuff is just a fad. It is much too dangerous for general use."

Thomas Alva Edison- Hide quoted text - - Show quoted text - If you have a Square D panel, you may be able to use a Q0CGK2 Generator interlock kit. This safely enables you to choose commercial power or generator power (but not both at the same time) for *all* you breaker panel circuits. You have to balance the load manually across the 2 poles, but for a safe, cost effective generator connection through a separate generator power inlet connector, it works well.
