EV charger not working or charging slowly — Barcelona, Catalonia
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.
Waarom dit veel voorkomt in Barcelona
Many pre-1990 Eixample and Gràcia buildings still carry undersized or outdated wiring that fails current REBT standards, and panels frequently lack the residual-current devices required since 2002. Lifts retrofitted into stairwells and patios add complex shared electrical infrastructure, and any installation work requires a GVA-equivalent Catalan completion certificate filed through the Generalitat.
