I've been asked to fit a supply for a 8.5kw shower. The existing supply comes into the house via an outside 'service box' containing the electricity meter. The tails go thro the wall into the kitchen to a consumer unit located in a cupboard in the kitchen. The kitchen is all fitted and tiled. The consumer unit has no RCD protecting the circuits and no spare ways. The house owners don't want the consumer unit changing (thank goodness coz access is well nigh non existant). I'm thinking of fitting a shower consumer unit. But where can I fit it? The onlt place I seem to be able to locate it would be in the service box where the electricity meter is. I've looked at the brb and can't seem to find anything saying I can't fit it there. Has anyone got any knowledge of anything that would prohibit the shower consumer unit being fitted in the service box any other ideas?
