Can I add an isolated ground bar to this?

ECGB5 or ECGB10 can be field added to this unit. These are ground bars, but they are not insulated.

Can I use this as a generator inlet if I use 100amp and 30amp breakers with the lugs feeding my indoor panel? Is there an interlock kit that will fit?

Should be able to find an interlock. This one's rated for total 125A current, so should work for what you need on 100A service. Surprised you still have 100A. Assuming old home or mobile home in your case, like mine.

Can this run a qf260a circuit breaker and a q3020 circuit breaker

Short answer is yes. Please have a licensed electrician do the work. Keeps the fire insurance companies happy! Greg

Pool sub panel

Used this as a sub panel for pool equipment. Worked fine

Great remote load center, just what I needed.

Well made and quite acceptable. I am using it for a remote panel addition and it works out great for me. It would have been better if the box was made with stainless steel for outside installation. Perfect little load center otherwise.

Does the job

I bought this box to replace an old hot tub subpanel (that was an identical model) that the previous homeowner had gutted for some reason. Works great so far and now I have power in my shed. As others have noted, it doesn't come with a ground bar which is a bit odd, but you can pick one up (any brand) at Home Depot for a few bucks and install it in the box.

Good box for my spa disconnect

Good box for my spa disconnect. Was able to install 40A GFCI breaker and pigtail. Just what I needed.
