Electrician FAQ for Seville, Spain: tripping, prices, the boletín and EV charging

Electrician FAQ: the questions people really ask

We did not make these questions up. They are the ones people type into Google and post in expat forums, and the ones we hear most when someone calls us. Each has its own page with a short answer in the first sentence, then a longer explanation with the regulations where needed, links to the related service and to the glossary terms.

How the questions are organised

• Faults and emergencies: why the RCD (GFCI) trips, what to do if it will not reset, what to do when the power goes off and how to tell whether the fault is yours or the distribution company’s. If the fault is happening now, go straight to the 24-hour emergency electrician.
• Prices: what an electrician charges per hour in Seville, what a boletín, a fuse board or a full rewire costs. All the figures are on our prices page.
• The boletín, potencia and regulations: when the boletín is compulsory, how much potencia contratada (contracted power) you need and the difference between an RCD and a circuit breaker.
• Electric cars: whether you can charge on a normal socket (outlet), how long it takes, what it costs and which grants are left in 2026. Start with the home EV charger for a house.
• Energy: what solar panels cost on a house in Seville.

Answers based on the regulations

Electricity in Spain comes with plenty of myths: that an electrician “authorised by Endesa” is more official than another, that the MOVES grants are still open, or that you need your community’s permission to fit a charger. In every answer we cite the rule that applies (REBT, ITC-BT-52, Horizontal Property Law, Building Code) and review it when it changes. If a technical or Spanish word is new to you, look it up in the glossary.
