    im doing my first private job next weekend for a mate he is going open a shop and is renovating it and he needs two a 110v transformers installed both have four 16a outlets and and two 32a outlets and are all protected by there own mcb i have bought an temp rcd board unit 2way for the job and the main switch is rated at 63a 30ma rcd but does this mean i need to pick up a 63 amp supply from the main board or can i get away by using a spare 50a mcb from the board or even 40a? or even get a lower rated rcd and what size mcb would you recommend for supplying the two transformers?
    any suggestions will be welcome thanks
