Installing an outdoor power inlet box for a generator.

Installing something like this on my house for a 3.5kw generator with an interlock kit.

Are there any codes as to where the inlet box can or can't be placed? Distance from ground? Distance from plumbing? etc.

I can't find any vinyl recessed block big enough to hold the inlet box. I am going to use a jumbo mounting block. Is this OK?

What's the best way to ground the generator? Can I bound a 12 gauge wire to the grounding rod and connect the other end to the generator's grounding terminal? Would that suffice?

Thanks for the help!

The connecting plug is a complete surface mount box system. It has knockouts in the back and the wire comes directly into the back.

The generator does not require a ground or ground wire. You should be using a four wire cord set and all connections needed are included in that cable.

You'll need to run 10-3 w/gr. cable from the connecting receptacle to the transfer switch.
