EV ChargerFaults
We’venoticed agradual increase in blown fuses
from EV charger installationsatresidential
properties.
installing the equipment checks that your home has
sufficient capacityfor the chargerand your home’s
average consumption so that overloadingwillnot
occur.
Astandard residential EV charger can draw 25 Amps
per phase, whereas most household fuses are 32
Amps –leaving littlecapacityfor the house itself. If
someone at the property turns on atoaster,kettle,
heat pump, or oven at thesametime as the charger,
they caneasily blow afuse.
