generator and transfer switch box
 
We had our 1st power outage 2 days ago...I went to buy a generator, at least for my sump pump and the 2 fridges
Now, power is back on but I was thinking about installing a transfer switch box (Reliance 3006HDK)
I want to have the sump pump, the 2 fridges and also my furnace running off the generator
The generator I bought is a Ridgid, 3,600 Watts continuous and 4,500 W peak
Will this be OK?

What brand panel do you have?

You may be able to find an interlock device for it. It will allow you to choose what you want to run, on any circuit. It basically offers increased flexibility.

I am not sure about the brand....It's a pretty neat panel though...
I am not sure to understand what you mean (sorry, I am french and not used yet to the US standard...!!!)

Some panel makers have what are called "interlocks" that you can install. Basically, it allows you to use your existing panel as a transfer switch.

The interlock prevents you from having the generator and utility power connected at the same time.

One advantage of the interlock is that you can choose which circuits you want to run. You aren't limited to the typical 6 circuits that some transfer switches have.

Example: You don't need power to your furnace in the summer but you might want power to another circuit to run a window air conditioner or even several fans.

All within the limits of your generator of course.

It's a General Electric from 1984 I guess (age of the house)
Does that mean those interlocks are additional items to install or the replace the breakers?

AandPDan 01-31-2013 07:58 PM

In many cases it is just some hardware that is added onto the panel box. You'd need to add breakers for your generator inlet - where the power comes in.

You need the exact model off of the panel box. If it's available it is usually cheaper than a transfer switch panel.

french_guy 01-31-2013 08:03 PM

This is what I am seeing on internet
It is basically a plate that slides up and down that authorize to have the main breaker OR the new generator breaker....Is that correct?
This seems to be the PROS (simpler and cheaper)
What are the CONS?

AandPDan 01-31-2013 08:10 PM

What you see is correct.

I don't see any "cons" in using one, only advantages.

Check with your local wiring inspector. They will tell you if they approve it or not. It shouldn't be a problem - if it's a GE interlock. Some of the after market ones may be a problem.

I found a website where they sell kits
http://www.interlockkit.com/genelecmain01.htm
It's around $150 for my panel.....Seems expensive for 2 pieces of steel !!!
The breaker for the generator, is it a regular 2 pole breaker?
My generator delivers 30A (3,600 W continuous and 4,500 W peak)
What size should be the breaker?

AandPDan 01-31-2013 08:28 PM

Check with GE, seriously.

I agree, the other IS a lot of money. If you have no alternative though it's still cheaper than a transfer switch.

For example: I have a Murray panel. My interlock was $45.

french_guy 01-31-2013 08:37 PM

Check with GE.......For the size of the breaker?
I would say it should absorb the peak, no?
So 4,500 / 120 = 37,5 Amps????
Should I be 50 Amps?

About your furnace....is it a gas furnace? If so, you will be ok with that generator and that transfer switch, but you won't be able to use the air-conditioning or power a heat pump.

french_guy 01-31-2013 08:41 PM

Yes, it is a gas furnace.
I can handle too hot in the summer w/o A/C, but too cold in the winter w/o furnace..............I can't !!!

The interlock seems a very good idea, I just need to find the model for my panel and know what rate should be the generator breaker !!

AandPDan 01-31-2013 08:50 PM

The generator breaker is sized for the generator.

What outlets do you have on it? 3600 watts continuous = 30 amps at 120 volt.

Don't base it on the surge capacity. Can you do 120/240 volts on that generator?

french_guy 01-31-2013 09:01 PM

No, it's only 120V @ 30 Amps.....(I can still return it though, I have 30 days at Home Depot)
It's a Ridgid, and here are the specs:
