Running a portable generator 150' away from the house


Will hard wiring a manual transfer switch using 10 gauge wire running underground about 150' wired to a 30 amp (4-prong) power inlet box connected to a 7500watt generator work?

Yes, but I'd bump it up to #8.

If it's portable why not bring it closer? That's a long run, and 8/4 isn't cheap.

I am guessing he has a shed to house it in bad weather and/or maybe also does not want the fumes and noise at the house.

Calculate what is going to be your total load, and then worry about voltage drop.

That's right. I want to use the shed that's in the back yard.

i ran #6-4 wire on a 3500 genny 100' between the garage and the CB panel not even close to what might be considered a load on either leg in the depth of a blackout yet...but over sizing the run out doesn't hurt if you have 115v out there already mounting an emergency light right above the genny makes it easy on the night time flip when you drop the pole..then when you start the genny you have your typical 100watt bulb going IF NOT... filling gas..checking the oil with a flashlight in your mouth is BS

I second Biggles' recommendation for an emergency light above the generator. You can pick them up cheap or free used, and it's SO NICE to have automatic light around the generator when the power goes out.

Then you need another normal power feed to maintain the battery pack.

I assumed the shed either has power, or would have power when he's done with this project. Helps to have a trickle charger for the generator battery, too.

Mine is about 100' away, and it works great! Really cuts down on the noise. Here is a pic of my little generator house in the woods.

Hey biggles,

How did you connect the generator to the CB panel? Did you disconnect the neutral to ground connection in the generator?
