Re: Interlock Murray panel

It depends on what kind of inlet. For the Reliance you would end up forming a "J" shape to reach the inlet (down, over, then up to the inlet), otherwise there are others such as this Bryant:

That just installs into a standard box.

It doesn't look like it has a top knock out, too bad.

But I don't understand the big deal with the reliance transfer switch.

It's so popular, but costs 250$ and only has 6 circuits.

On the canadian Home Depot website, you can buy a 18 space transfer switch for 200$ and have 50$ to spare for the inlet and wires.

I don't see anything like that on the american home depot website, but I'm sure they exist.

the one I'm looking at is like $180

I would suggest one like this:

Yeah but that's only one circuit, no?

*edit
Ok does not seem like it but how does this one work? It seems like it's wired after the main?

It's a whole-panel switch, it works in place of a main breaker with the same function as an interlock kit. Basically like this:

Meter -> T.Panel -> Main Breaker
Generator ->

You run the 10/3 or 8/3 line from that to your inlet. This transfer panel allows you to use your old panel without a whole lot of modification without the risk of back feeding the utility line. The generator itself has a circuit breaker of either 30A or 50A which would provide the over current protection if need be. Just make sure that the neutral-ground bonding is removed.

Got it, It would not be until Dec until I get a higher wattage generator providing we don't get a massive snow storm stores can start building up a fresh supply of generators.

The interlocks still use the generator input plug, no?

I assume those kits are wired after the main? And I really haven't checked but were can you find one of those watt meters that goes over one of the wires? I assume it's nothing but a current measuring device but in wattage instead of amps.

Interlock kits are made by your panel manufacture and are basically a metal bar on your panel that switches between two double breakers on that panel (main and generator). Same concept as that panel I showed you, just as an "all in one" solution.

Well you could just use a clamp meter and measure the amps and do the math from there honestly (V*A=W, ignoring power factor at the moment).

Interlock Kit



Transfer Switch Type 1



Transfer Switch Type 2



Transfer Switch Type 3



Transfer Switch Type 4 (Automatic)



Note these aren't official "types", rather just show the different types of transfer switches.

reply to Subaru
hah automatic would be nice but a little too much on her house..

the interlock seems to be simple

I assume I need a open breaker location but given how it is on my panel I might have to shift some breakers down?
