Hi, Is there any argument to having a panel, and main breaker, rated much higher than the supply from the HYDRO company? eg cables from Hydro size what commonly carries say 100A spliced at the mast into say 200A rated size cables. This means that there are circuits total more than what seems to come from the Hydro (old building - little control and lax rules applied in this area)

Hi, Found a Hot Water tank without a Pressure Relief Valve. (PRV) during an inspection. Do some Hot water tank designs not need a PRV??
