Answer: 
The generator interlock kit part number QOCGK2 can be used for the QO30M150 Series G1 load center, BUT the Generator kit part number will NOT be shown on the labeling of this  load center and labeling CANNOT be obtained because the load center is old and obsolete.

Answer: 
Schneider Electric does not recall offering a series 04, CQO160M200C Load Center. If you have a series S04 which has the QOM2200VHL Main Breaker installed then the QOCGK2C is compatible. It interlocks the QOM2 2-pole main circuit breaker with a back-fed QO 2-pole (15-125 ampere) branch circuit breaker. A retaining means is also provided for the back-fed QO branch breaker.

Generator Inter-Lock Kit for QO Indoor Main Breaker Load Centers is rated 4.7 out of 5 by 15.

I am an electrician with 40 years experience and don't work for Squared D. I have purchased electrical products including transformers, panel boards, circuit breakers etc for almost 35 of those years. The support from Square D, the quality of their products, the clarity of install instructions and the uniformity of their products have made me a loyal customer. The pricing of this product is not just based on the cost to manufacture. This is a part that will often be installed by non-electricians, so there is an extra element of risk to the company. The design and prototype testing costs are also in the price. I have no hesitation in recommending Square D products (and their people).

It is too big. The larger load centers have 2.0--3.0 inches between the opening for the Main Breaker and the openings for the branch circuit breakers. The 100 Amp Load Center only has about one inch between the two openings. I returned the unit to the store because it did not work. It is possible that the HOMELINE interlock may be small enough. --- Shadow738

Rated 5 out of 5 by from Excellent product Simple to install and is a perfect safety for anyone installing a generator without an automatic transfer switch.

Rated 5 out of 5 by from The easy way to connect gen power to a house. Getting an interlock kit like this that fits your house panel is the cheapest, cleanest, and easiest way to get generator power to your house (that i've found). Obviously this one works just with it's brand & models of panels, but there's probably one from your panels OEM as well. You only add one cable into the panel (for the incoming gen power), so there isn't a spaghetti mess of wires added when you're done (as well as extra panels to confuse you later with what panel controls what circuits, etc). With this, you can send gen power to any house circuit you want even running some for a while, then rotating to others (versus having a very limited selection with add-on panels and nothing else besides that selection can ever be run). Just be careful about how many things you turn on at once while on gen power which you control from the breaker box (you may want to plan a system labeling certain breakers with color coded stickers or such to know what they run & how important are they). The cost of this and other parts needed can easily be less than that of the add-on panels alone. So I see nothing wrong with this and virtually everything I've heard like "You can easily overload your gen this way" can be countered with statements like "Anyone can plug in too many things at once, so you need to watch your loads regardless of your system". The only problems you may face is you need 2 extra breaker spaces & must free up the breaker spots at the top of the panel (spaces 2&4) for the gen breaker, it must go there. Also, the panels these go on must have a "Main" breaker at the top that disconnects all utility power, if you don't have that you can't set this up. If those aren't a problem, then this will be as easy as anything else to install and give you the most options for how to utilize your generator power when needed.

Rated 5 out of 5 by from Simple, not expensive alternative to manual trasfer switch when you know how of adequatly distribute house loads to portable generator. A safe and inexpensive alternative to installing a manual transfer switch for portable generators to prevent potentially dangerous back feed to the Utility's Electrical Distribution System. It took me about 1 hr to carefully install the manual lockout. Supplied drilling template and instructions were spot on. Operational instructions and decals were clear and concise. Also saved money purchasing from HD rather than local Electrical supply although I ordered from them first and never received a call for pickup. Since I worked on live conductors for a Utility Company splicing up 750 MCM live, I felt comfortable working live but with caution. I don't recommend the same for the everyday DYI person. Personal Protective Equipment ( PPE ) is a must.

Rated 5 out of 5 by from it works for square D 200 amp interior panel just followed the directions, took about 45 minutes and works just like it was engineered to do,
Date published: 2016-05-17
Rated 5 out of 5 by from Good, Simple Product I liked this inter-lock kit. It was easy to install it even give you the template to drill the holes. I opted for this over a transfer switch for two reasons: 1. The cost of the transfer switch and it's limited amount of circuits 2. The ability to turn on any breaker I want in my box to power up anything. The transfer switch limits you to how many circuits you can have or might want to use.

Rated 5 out of 5 by from Good Value The kit is as advertised and the directions very easy to follow. Installation took about 45 minutes, I'm slow, and the only additional items to purchase were the 3/32 and 3/16 inch drill bits. The price is reasonable compared to the much more expensive transfer switches and the configuration of this kit offers more available circuits as long as you keep demand within the output of your generator. Square D engineering is obvious in the simplicity of the interlock. I recommend this product
