Searching for breakers for W0816B1200CT. We have two 200 amp panels with this number fed by a 400 amp service. We have two interlocks ECSBPK07. We cannot see how they will work. Need help. Many thanks.
Asked by: Cowboy
Cowboy. Any Siemens breakers are used for this panel. In terms of getting the interlocks to work, you need to make sure your main breakers are a QN, QNR, MD-T, or MD-TR style Siemens breakers. Thanks,

Rated 5 out of 5 by from Great product. Much cheaper then a transfer box. Had to modify it to not loose two circuit breake... Great product. Much cheaper then a transfer box. Had to modify it to not loose two circuit breakers that are to the right of this interlock kit. Previous buyer had pictures and instructions on how to do modify it. That was a great help!

Rated 5 out of 5 by from Standby Power Interlock Kit for siemons distribution box The Interlock kit was very easy to install and fit perfectly. I would recommend this as an easy and safe way to prevent back feed. Picture shown includes breaker which is not included in purchase.

Rated 5 out of 5 by from Does the job, great price! Professional look Fits my Siemens panel perfectly. I verified with Siemens with my panel number. Works perfectly! Looks better and costs less than the aftermarket products available. Only downside is that is that it must be located on 2 breakers on the top left side of the panel and uses the spaces of 2 breakers on the top right side. The spaces for 2 top right breakers must be empty. Had to relocate the existing top right breakers. I was able to cover the 2 empty right side slots with standard plastic slot covers slightly modified. As a homeowner I installed easily. Good instructions. Important: Feed wires to the 2 generator breakers must be affixed before the interlock is installed over the breakers. Interlock blocks access to the feed wire connections.

Rated 4 out of 5 by from Easy and inexpensive alternative to seperate transfer switch! After much research I found this product. I live in an area that frequently loses power and have wanted something like this for a long time. I found a lot of reviews on this product. It is true, the product hangs into breaker 2 and 4, so you will have to move them. Luckily I had plenty of room to do so. I just need to get a couple of covers to replace the temporary duct tape. I found that I did not need to alter the panel cover as mentioned in some reviews. If you turn off both breakers and move the slides, you can put cover on without altering it first. The next step is to test it with a generator, but see no issues with it working. Overall a reasonably priced, easy install alternative to putting in a seperate transfer switch.

Rated 5 out of 5 by from Works as intended. Easy mod to use spaces to the right. This interlock does exactly what it is supposed to do and is very easy to install. One complaint by several reviewers is that with the interlock in place, the two breaker slots to the right can not be used. This is true, however it can easily be modified to allow full use of all breaker slots in your panel. See the attached pictures for details on how to make this simple modification...

Rated 2 out of 5 by from Functional but poor design and marketing This interlock kit was very easy to install it's of decent quality. The cost (of ANY brand interlock kit) is a joke for a few pieces of sheet metal and some screws. There are however, 2 additional major disadvantages with the Siemens model versus the others. What makes it worse, these little tidbits were nowhere to be found in any literature. First, when the unit is installed, it renders the 2 spaces just across from it unusable. That's a pretty big deal when you are installing into an existing panel and possible one that is already full. So basically, you are looking at 4 spaces needed for installation. If that wasn't bad enough, you are unable to use fillers for the 2 additional spaces it takes up. The metal frame extends into that area part way. Had it covered up the open spaces completely (a very easy design modification) I would be a little more impressed. Second, after the unit is installed, the only way to remove the panel cover is to shut the main breaker off. Not a HUGE deal but it's another point that should be listed in the literature for the product and it's the only interlock kit that I have ever used so far that makes you shut off the main breaker to do so. If I didn't know any better, I would say these 2 little items may have been intentionally left out of any type of advertisement or brochure.....but a major company like Siemens would never do that, would they??

Rated 2 out of 5 by from Quick install This product dose the job and is easy to install, however it is poorly designed and causes you to loose two additional breaker spaces more than just the two used for the generator, and partially covers their spaces so that breaker filler plates will not fit, you must screw a piece of metal to cover their openings, unless you have never used the 4 spaces next to the main circuit breaker

Rated 3 out of 5 by from Concern about panel access I understand and accept that the #2 & 4 breakers must be moved and had done so, but my bigger concern is how the interlock snaps into the breakers. From looking at how the interlock snaps into the sides of the breakers behind the metal panel, once the breaker panel is back on, it looks like it would be impossible to get that breaker panel back off in the future if needed. Am I misunderstanding something or is there a way to remove this interlock if needed?
