Generac Load Manager

Sounds too me like something is not hooked up.

Do you know for sure your generator cable is good? Check that for continuity.

Check the outside receptacle wiring for possible bad connection or broken wire.

Or, If your capable, check the wiring in the basement and see if you have 220V coming from the generator.

Make sure the transfer switches are wired into the circuits. There should be a bunch of extra wires running from the transfer switches to the load centers, and they should be spliced into the circuits they serve.

I have put these in, and they are very basic and simple, they should work fine when you find the problem.

I installed this same system at my house and it is a simple installation and works well.Most likely the center two circuits power a 220v device like a well and two of the other circuits are the furnace and refrigerator.

I'd first confirm that the generator cord is wired correctly to deliver 220 volts to the transfer switch box, especially if it was wired for a different setup in the past.

I am starting to think something is not hooked up also. I threw all the switches on the load manager to "off" and "gen" (without the generator running) and nothing in the house went off. I'm sure the refrigerator or sump pump outlet would be on the load manager, but both of them were still running. I will pull the panel to see if anything is wired.

A 5000 W generator is small for a house, how large is you circuit breaker panel?

I have a good sized house, with 2-40 circuit panels, (75% full) and if I told you what I can, and do, run off of a 5500W heavy duty Generac, you would not believe me.

They are not wired if they do not go dead when you switch them like that.
That is not a big problem, you simply run the circuit you want to transfer through the transfer panels, they are prewired so it goes pretty fast.

Yeah, something doesn't sound right if that's the case. Easiest is if it's not hooked up at all. If someone hooked it up, but did it wrong it could be challenging to sort it out. Let us know what you find.

The Generac load center switches are wired BETWEEN select circuit breakers in the main panels and the loads in your house. If you flip the switches in the load centers to "Gen" without the generator connected, and nothing happens, then they are not wired into the main panels between breaker and load. If they were, as you surmised, those items wired into the load centers would stop operating when you switched.

I would guess that if you pull the front covers off the two main breaker panels, you might find a coil of multi-colored wires just setting there that come from the flexible conduits that connect the main panels to the generac panels. This would indicate that It was a project that was started but never finished. Or you may find the wires routed to the vicinity of certain breakers and they are setting there with a wire nut on the conductor end, or two colored wires nutted together. This would indicate that it has been deliberatly disconnected by the previous owners to limit their liability. IE: If you want to use it, you need to re-wire it, which now makes it YOUR responsibility...

You'd think out of sixteen, one would be drawing power.

I may be wrong, but it looks like each panel has 6 single pole circuits. That means you have a maximum of 12 with the two panels, not 16.

It also looks like the installer used the factory cable to feed two units from the outside plug. It is meant for one unit. I think that exceeds the factory cable rating. The factory cable could melt before any of the breakers trip, especially if you use a generator that exceeds the cables rating.
