Re: Interlock Murray panel

Awfully expensive for a couple pieces of sheet metal, but then again it's for a limited market.

It is expensive, but it's due to the cost of testing so it can be UL listed. Without that, I don't think building inspectors can allow it to be accepted as code compliant.

the panel in ur picture has top-down for the main breaker.

doubt it will work

why wouldnt it, ive seen many interlocks for horizontal breakers that will stop a vertical main from being operated. the interlock would need to slide to the left and block the main, simple as that.

If all you want to run is the boiler/furnace, I'd put one of these in. »www.homedepot.com/Electrical-Bre···wrZG9KK0

Might be good for my friend who might do that later but in my case at a family member's house I'm going to be getting a larger generator after December so use for power outage and out in the field.

So in my case I would need to do whole house so I would still need the interlock.

You would need the interlock, or a full blown transfer panel.

Correct, I should tell my friend about it.. I took my Generator to his house yesterday just so I can show him you can use it for muti uses like powering stuff like my heater I ran yesterday when it was chilly, hardly could hear it running..

Anyways I will just do the interlock and just deal with the price, I might have to email the guy on that interlock site to see if I can use that interlock that has a 4 handle main Murray on my box that is a 2 handle main.

I assume all 100 Amp service panels just have a 2 breaker main?

Depends on the 100A panel and the age, but most main breakers are just large single breakers (larger than any of the other breakers in the panel).

I think he meant 2 breakers as double pole.
Then yes, they're not different from their 200A counterpart (of the same age/brand).

I often see identical panels rated 100A and 200A, the only difference is the breaker rating.

These are not 2 breakers in tandem but it's a single breaker with a bar to connect the both of them.. I'd have to double check to be 100% but at least that's what I saw, but having said that I can't see why the one on that site wont work for mine.

Your main breaker is a set of handle-tied (Edit: not tandem) breakers rated at 100A, like this:



Whereas other panels have a main breaker like this:

gotcha, and they make beakers for backfeeding right? Or well that's what I heard.

Yes, depending on the manufacture.

Should I be looking for a certain brand breaker? I noticed on that interlock site they have piggyback breakers and backfeed breakers.

I think Siemens breakers are said to fit.

Any brand that fits, Siemens is good though.

Still haven't heard back from that site with the interlock kit.. I will just guess he is busy or customer service is lacking.

I looked at the interlock kit site. I don't think they have one for that panel. Murray panel should only use Murray breakers. They are still manufactured and widely available.

Note of interest: Even though Murray and Siemens breakers are the exact same, made in the same factory and on the same line - Murray breakers are listed for use in Siemens panels, but not vice-versa.

Also wanted to make a comment about interlokkit.com, not all of their interlocks "fit like a glove". The last one I installed had to be filed down. I don't like doing that. I would also suggest buying the manufacturers breaker retainer rather than using their included ty-wrap method.
Their products are listed and I've never had an inspector reject their paperwork.

In your case, you may have to use some other option other than an interlock. While there's nothing wrong with that panel, it's age will work against you when trying to track down an interlock.
