I'm interested in setting up a secondary CU on the output of a UPS, to run assorted loads around the house. (Emergency lighting, network gear, ...) However, I'd like some small MCBs to cut out the various low-limit circuits at some worthwhile point. A 6A MCB is essentially useless, as the UPS will trip off way before then.
0.5A, 1A, 2A might be of use.A quick search does not reveal sources of these. Any thoughts?
