Customer Questions & Answers

do you carry the 200 amp, main circuit breaker to feed a sub-panel from this SES?

I realize there is a 200amp main for the load center located within this SES, but there is also space for a second 200amp main breaker to feed a sub-panel. Do you carry this breaker, what is the model # and how much does it cost?
Asked by: NRADave1963
Additional 2-pole 200 Amp service disconnect for field-installation, with 25kA short circuit current rating, is QDL22200. Other short circuit ratings are available, if required. Please contact your retailer for quotation assistance.

Customer Reviews

Homeline 400 Amp 30-Space 40-Circuit Underground All-in-One CSED is rated 3.5 out of 5 by 2.
Rated 5 out of 5 by from Good choice for 400 Amp installations I had the comparable Eaton model on order from my electrical supplier and spotted this at my local Home Depot in an inconspicuous location high up on a shelf and decided I'd pick it up and compare the two in making the decision on what was going to be going in to the new home I'm building. I work with 200 Amp panels all day long and 400 Amp panels on occasion as a solar contractor so I've seen my share of panels from the various manufacturers and in general I prefer the Eaton models when it comes to service mains. Looking at them side by side they are functionally identical and either will do the actual job as a load center equally as well but I've decided I prefer the Square D model to the Eaton for the following reasons: 1. Edge finish - The steel edges are rounded and caught my hands in working with the panel and there were fewer snag points. When you reassemble the panel the Square D's breaker cover slides in more smoothly partly because the steel edges are rounded better and the paint seems to be thicker/more durable. 2. Finish hardware quality - The latches and handles on the Square D are a notch or two better than the Eaton with the exception of the main door hinges where the edge goes to the Eaton as you can remove a set screw and slide the entire door upwards off of the hinges (if you don't end up with stucco in the road once the home is finished - I've seen this be an issue before). 3. Appearance: The Square D has some bevels and bends that give it a little bit of a cleaner appearance. 4. Price - Home Depot's retail price is 25% less than what I paid from my wholesale electrical supplier. About the only downside to the Square D model is that you cannot get breakers from other manufacturers to seat correctly which means you're limited to using Square D's Homeline breakers. On new construction this isn't an issue since you're using all new hardware anyway. If you're doing a panel upgrade (say 200 Amp to 400 Amp) you will need to factor in the cost of new breakers if your previous panel isn't a Homeline model. This is probably only an issue if you've got a number of expensive AFCI or GFCI breakers in your current panel and want to be able to reuse them. I make it a point to stick with the breakers that the panel manufacturer lists for use in their panels. As for the 2-Star rating from another reviewer, I think they've got to factor in the reality that 400 Amp panels are not garden variety DIY animals and you step in to a different class of connections that are needed on the utility side. If you have a good relationship with your utility lineman they will often take care of these connections for you. Giving the panel itself a bad review on account of Home Depot not carrying the crimps (that require a special tool to install) is pretty unfair.

Rated 2 out of 5 by from Doesn't come with termination lugs I purchased this panel from Home Depot and after I installed it I asked for me local electric company to come out and inspect the installation. When the inspector arrived I failed the inspection because it was missing the termination lugs for the service input that the electric company terminates to just before the Meter. I returned to Home Depot to inquire and was told that the lugs are not available to purchase thru Home Depot. Beware!
