    Hi Bill,
    I’m installing a generator inlet box on the exterior of my garage. There is an exterior water faucet about a foot from the ground. How far away from the faucet should I install the inlet box? Thanks.

  2. Dave Rongey says:

    Hi Victor,
    With all the generator panels and transfer switches installations I have done I have always located to receptacle for the generator cord on the outside near the generator. As you nay know, a generator may not be located indoors for a number of reasons, most of all carbon monoxide and locating the generator receptacle indoors could be misleading. Ask the question to your local building department when you obtain your permit to be sure.

  3. Victor says:

    I want to run my portable generator about 10 feet in front of my garage. Can I install the flanged power inlet inside the garage (connected ro the transfer switch by Romex run inside the wall), or is this against code and needs to be installed outside the house? I live in CT.
    Plugging the extension cord inside the garage would be safer (dry) but I don’t know if allowed.


  4. Dave Rongey says:

    Hi Bill,
    If the 10-4 SO Cable will be permanently installed then it would be best to protect it with EMT or PVC conduit which is strapped and supported. To prevent overheating, the size of the conduit should provide the same amount of free air space as the size of the 10-4 cable.

  5. Bill Heisler says:

    I’m about to install a generator transfer switch with an outside power outlet for the generator using 10-4 SO wire which will run along sheetrock on the inside of the garage wall for 6 or 7 feet. Should this wire be run in conduit or is it possible it will overheat if it is? Thanks.
