Are you talking about static heaters or portable heaters if it's the later I doubt you will find much in BS7671 most likely find the info you require in the CoP ISITEE (PAT CoP)Please: do the regulations say that heaters must have A-T switches?
Maybe some types of heater? Thank you.
Nothing to do with PAT. Manufacturing standards would be more relevant.Are you talking about static heaters or portable heaters if it's the later I doubt you will find much in BS7671 most likely find the info you require in the CoP ISITEE (PAT CoP)
Never said it was, just saying to the OP that he COULD get some information from the CoPNothing to do with PAT. Manufacturing standards would be more relevant.
