We do home cinema installations in Santa Coloma de Cervelló. We visit your property, assess the job, give you a clear price, and get started. The RCD protects people. It detects the difference between the current entering and leaving the installation. If this difference exceeds 30 milliamps, it means something or someone is earthing current, and the RCD cuts off in less than 30 milliseconds. This is what prevents electrocution when a fault in a washing machine causes the metal casing to become live and you touch it.

How we work

It starts with a technical visit from an authorised electrician who diagnoses the fuse box and installation. They measure the actual cable cross-section, identify overloaded circuits, and detect any existing earth leaks. They provide a fixed quote with a breakdown of costs. To add a new socket where there was none, there are two approaches. The first is a chased conduit. This involves cutting a channel in the wall from the nearest socket to the new point, running the cable inside, and then filling the chase with plaster. It's the visually cleanest option but requires minor building work and repainting the wall. Timeframe: 4-6 hours plus wall repair.

When to call for home cinema in Santa Coloma de Cervelló

These two components are found in all modern fuse boxes but protect different things. The circuit breaker, also called an automatic switch, protects against overloads and short circuits. If you connect too many appliances to one circuit or if two wires touch due to a fault, the circuit breaker trips and cuts off power. Its function is to protect the installation's wiring and prevent fires. The fuse box has ceramic fuses instead of modern circuit breakers. The fuse box lacks an RCD or only has a main one protecting all circuits. RCDs trip frequently for no apparent reason, indicating they are aging. The fuse box has fewer than 4-5 circuits for an entire home. The standard is a minimum of 5 circuits (lighting, general sockets, kitchen, washing machine, bathroom, and air conditioning). The fuse box is overloaded, with no room for additional circuits to add electric car chargers or other modern equipment. A highly requested upgrade today is to combine a motorised roller shutter with an integrated roll-up mosquito net in the same housing. This allows both the shutter and the net to be operated independently, both concealed when not in use. It's the standard solution in modern new builds. For renovations of existing homes, it requires replacing the entire housing with a new, deeper one to accommodate both systems.

Materials and brands

Manufacturer's official warranty on the mechanism plus our coverage of the labour. Integration is done via an app. You download the manufacturer's app, connect the device to your WiFi, and then add it as an associated device through Google Home or Alexa. Once done, you can issue commands like 'turn off the living room light' or 'raise the kitchen blind,' and it works. Almost all modern equipment integrates with Google Home and Alexa, the two dominant assistants in Spain. Apple HomeKit has stricter certification requirements and limits brand choices. It also has its audience among iPhone users who prefer a closed ecosystem.

Frequently asked questions

How long does it take to install a new socket?
With an external conduit, 1-2 hours. With a hidden chase and wall repair, 4-6 hours plus paint repair.
Will my British or American appliances work?
Modern appliances yes (100-240V). Older heating or kitchen appliances may not support 230V. Check the appliance label before plugging it in.
Can I install WiFi smart switches?
Yes, with brands like Sonoff, Shelly, or Philips Hue. Installation takes 30-60 minutes per point if the existing box has space.
Are all LEDs dimmable?
Only LEDs with a dimmable label work with a dimmer. Standard LEDs will flicker or not turn on with a dimmer.
Is a power cut necessary?
Only from the affected circuit, not the whole house. Work on a specific socket or switch involves cutting off only that circuit breaker in the fuse box.
