Default Re: Earthing a part metal enclosure for mains transformer ?

There shouldn't be any significant "inrush" of current. I assume that the T/F is being used for some vintage radio pursuit. I.e. a resistive load, as opposed to a motor ? Many vintage valve radios only draw 200 to 300mA from the mains, so a 1A fuse is what I fit. That wee T/F is only rated at 50VA, so if it starts to draw 1A, 2A or near to 3A(approx. 750VA at mains voltage) - it'll seriously overheat. What is it being used for ?

Regards, David
