Customer Questions & Answers

I have a Square D panel Model # QON30M150 Series G1 which is about 20+ years old. Will the QOCGK2 interlock work on my panel?

Asked by: Ken
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.

Does this product meet the national electric code requirement for isolating the generator power from the main power?

Asked by: snowyminnesota
Yes, but each jurisdiction (town, county, etc.) is different, and some may not like it. The Main Breaker interlocks allow the customer to power anything fed by the main panel (and any sub-panels) but you can't power "everything." A 2500 to 5000 watt generator will power the "essentials" of a two-story house, but not central air conditioning or central electric heat. They will power the fan motor of a gas or oil furnace. The larger generators (5000 watts or more) may be able to power an electric water heater.

Is this manual transfer switch compatible with a Square D model # QOC 40MW225 Series 7 panel?
Asked by: Peter
Hello Peter, An interlock kit is not available for the QOC40MW225 load center. This load center was built before interlock kits were available. Regards, Customer Care Center

Generator Inter-Lock Kit for QO Indoor Main Breaker Load Centers is rated 4.7 out of 5 by 17.

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

The product was easy to install with the assistance of the included instructions. The components lined up faithfully with the load center cover. I found the pictures included with the instructions beneficial in proper orientating the components. I have not had to use the product at this point but the product prevents the main breaker and the backfeed breaker from being "on" at the same time. I did take one step not included in the instructions. I used a steel punch, guided by the drill template, to further mark the hole locations before drilling the load center cover. The only negative aspect of this purchase was that UPS lost the parcel on the truck that was to deliver it to my home. UPS tracking identified that the parcel had passed the delivery scan. As such I could not understand why it took almost two weeks for UPS to resolve the lost package investigation. When the parcel arrived it was damaged (cut open) and sealed with tape. The condition of the parcel prompted me taking pictures before I opened it. When I called UPS about the package they shared their procedures with me, but indicated they would only share resolution facts with Home Depot. When I called Home Depot Customer Service (they were very helpful and cooperative) they verified what UPS had already shared with me but also indicated that I had several options if the parcel was not found - at no further cost to me.

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 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.
