Your electrics, in plain English
Portuguese installations come with their own vocabulary. These are the words on your board, your bills and your paperwork, and what they mean.
- quadro elétrico
- The board where every circuit in the house starts. When it is old, undersized or unlabelled, this is where most tripping problems begin.
- disjuntor
- One for each circuit. It switches off when that circuit is overloaded or shorted, and each one should be labelled with what it feeds.
- diferencial
- Trips when current leaks to earth, which is what protects people from electric shock. Press its test button now and then to check it still works.
- terra
- The green and yellow conductor. It gives a fault a safe path so the RCD can do its job. Some older villas were built without one.
- potência contratada
- The limit on your electricity contract. Run the oven, air conditioning and water heater together above it and the power cuts out, even though nothing is faulty.
- E-Redes
- The company that runs the local electricity network in mainland Portugal and looks after the meters. If the whole street has no power, it is a matter for them, not for your electrician.

Lost power to half the villa the night before guests arrived. Trisis came out within the hour, found the fault and had us running again. Lifesavers.
Full rewire of our 1980s villa. Clean, certified work, fair fixed price and everything explained properly in English. Highly recommend.
