Interlock Murray panel

If you use an interlock, how do you know when the power has come back on? Seriously.

I have a small 4 circuit transfer switch that I use for my Honda 2kw generator.

No joke I was just sitting here searching interlocks and I had that very same thought about how would you know.

Adding an inlet is a lot like a two pole outlet. You'll want to locate near where the generator will run, of course, and add an additional ground conductor split-bolted to your house ground to connect to your generator's frame ground terminal. Also, ideally, the generator won't have an internal neutral-ground bond.

Adding the interlock will take some drilling on the panel face, not a big deal, and yes, the 3 KW generator sounds like it will be fine. Any other motors besides the fridge? Sump pump, well, septic dosing?

I'm using a transfer switch that is nearly identical to this unit:

I found one new in box on ebay for like $30.

Nope really basic house it's from the early 1920's she has city water the only pump she needs to worry about is the tiny pump on her boiler.

Then 3KW ought to be fine.

yeah I think so too she only uses CFL's in the house and the two largest loads would be the fridge and microwave, I did not check the furnace pump but it's really tiny I'd be shocked if it was more then 1/2 HP.

I thought the inlet box had to be located on the outside of the house?

I basically installed a "permanent extension cord", lol. There's an outside inlet, it's wired to an outlet near the transfer switch. When I need to use it I have a short cord that goes from it's outlet to the inlet on the front of the transfer switch, then I have a 12gauge extension cord from the generator to the inlet (an L5-20P).

It's not ideal, but it works and the price was right for the switch so I live with it. I just keep careful track of where those two cords are. The long one for the generator I used a L5-20R on one end so it can't wander off to be used a general purpose drop cord - hence using the L5-20P for the inlet.

oh... the link you gave me I just noticed the male end was not a L5-20P, see the panel is near the basement door like 6-7 inches away I would have to put the inlet box in the front since the side wall is all hard rock.

well I'm reading the manual here and they are talking about the hard wire installation now, and by up and over are you talking about the inlet box on the outside? it would be a bit over my head with the height it would just be simple to install the box behind the bushes because it would just be a direct run to the panel, I did that when relocating the power box next to the gas meter to the other side of the house.

It would be best just to have the plug in the front the bushes hide anything, the house had a addition added on in the early 80's or late 70's but the stone is like 7 inches thick stone.

The front is just siding, wood then the insulation then basement.

Here are pictures I just took it was hard to describe, I don't want it in the front for reasons you can see in the pictures.. front is street level, load it up and gone.

That's an old foundation on that house, old mortar for sure.

If you want it in the back there the best option is to go up a level, over through the wall, then drop the PVC down to wall height and use mason screws or construction adhesive to mount the box.
