With reference to 433.1.204 and cable as installed has min capacity of 20A if protected by a 30A or 32A. If the protective device is reduced to 20A how is the new minimum as installed capacity calculated or arrived at ? I've been looking in the Electrical Installation Design Guide, but the answer is avoiding my eyes.
I like the idea ebee of not having a dedicated rfc for the kitchen and or utility room but instead to have the two rfc circuits into the kitchen, say one each side or however it works out. This way it takes into account the fact that the rest of the dwelling takes very little so in theory, you could have say 60 A of potential kitchen load with the remaining 4 A supplying the TVs etc. The only downside is clarity on the CU to identify the circuits as I've only seen a few complying with the latter part of 514.9.1..............
