Totally perplexed, as I can't use my 3 pin Delphi charger (SMART EQ) in my garage as the charger unit fails to start charging (blue light flashes a couple of time then goes off). Oddly it works fine with an extension lead from my house? I've checked the sockets in the garage using an earth plug checker and all is correct. Garage cable runs from a 32amp MCB to a separate 100am board in the garage, with 2x 8 amp and 1 x 16amp mcbs. Everything else in the garage works fine, including my tumble dryer. HELP???
