consumer units

hi, i've been replacing quite a lot of wylex 60a consumer units for a landlord lately in 2/3 bedroom terraced houses as the tester has failed the installation coz they have cooker points in. is this absolutley necessary or is he just going overboard as it seems to me that wylex replacement mcb's would stop the cooker and ring mains drawing too much current....the usual arrangement is u/stairs light and ring circuit, d/stairs light and ring circuit and a cooker point with socket outlet in the kitchen...just 5 circuits

regards

I think the problem is with the main switch only being 60 Amps most main switches are 100 Amps or 80 /30m amp RCD also the old wyles boards are made from wood and a lot of them never fitted the fire proof backing

As this is for a landlord he is renting rooms or houses out to people and thus must be inspected annually to gain appropriate certification/insurance, to be honest i surprised he has managed to rent anything out without this being changed sooner!

The main switches are under rated The tails to the board will most likely under size There is unlikely to be any earth bonding either The sockets and cooker should be RCD protected too Also expecting/allowing your renter to mess around with rewireable fuses is not good

Essentially all this will be rectified with the fitment of a new board of split type! This is to be done by qualified/experienced persons and as your asking the question as to why, i do wonder if you should be changing boards!!!

tails NOT too small, board is upto british standards, cookers DO NOT have to be on rcd's, please refer me to the reg that states this, sockets DO NOT have be on rcd unless expected to supply outdoor equipment, the cooker frame has to be tied to the main bonding which it is. this is a small two bed terrace house. if you had read the question properly, i stated that wylex replacement mcb's could be used. this would stop the tenant messing around with fuse wire as there would not be any!! the landlords insurance does not require the electrics to be to bs 7671 standard and an inspection not even necessary, he is only having them inspected out of moral needs. please tell me a particular reg or law that actually states that 60a wylex consumer units are not to be used. as 20a x

2(small rings) + putting both lighting circuits on 1 ring 6a + 10a for small fixed cooker is less than 60a therefore unit acceptable. less of the cocky shit and some facts please.
