Advice about PHEV car charging. Discussion ThreadAdvice about PHEV car charging. Electrical Advice
We have 2 PHEV vehicles in the family which we charge overnight in the garage, each car plugs into a normal 3 pin household socket. There is a small garage Hager consumer unit in the garage which has a 16A MCB protecting all the wall sockets which are wired with 2.5mm cable. The car chargers are 2.4kw with a current max rating of 10A. One night the 16A MCB tripped but we're unsure why.
My question is: Could the reason be that with both cars charging at the same time on the same circuit that it was being overloaded? If so could I safely replace the 16A MCB with a 20A or 32A MCB without causing any other problems.
Also the cable which supplies the power to the garage from the house is protected with 16A MCB, would I need to upgrade that also?
