EV charger not working or charging slowly — Delft, South Holland
A home EV charger (Level 2, 240V) that stops working, trips breakers, or charges slower than expected usually points to an electrical issue rather than a charger defect. Common causes: the dedicated 40–50 amp circuit breaker trips due to a loose connection or undersized wiring, the GFCI protection built into the EVSE trips from moisture or a ground fault, the outlet (NEMA 14-50) has loose terminals that overheat, or the charger's internal contactor has failed. Before calling an electrician ($75–$150 service call + $50–$100/hour), check the breaker panel — if the EV circuit breaker has tripped, reset it once. If it trips again within a day, the circuit has a fault that needs professional diagnosis. Slow charging (getting only 15 miles/hour instead of the expected 25–30) often means the charger is throttling due to a voltage drop — the wiring run is too long or the wire gauge is undersized for the distance.
Why this is common in Delft
Electricians in Delft switch between careful upgrades in older (often protected) buildings and standard consumer-unit work, plus the growing wave of EV chargers, heat-pump circuits and solar tie-ins.
