Planning to do the dedicated mains spur and ready t order the bits required. Just wondering which way you guys have done yours. 6mm t and e to be used. 1. Simply use a spare spur on the existing consumer unit. or 2. Fit an additional new consumer that is wired in parrallel to the existing consumer unit and use spur from the new consumer unit. (RA method) Any views / comments appreciated. Iain
