Question 1

Why does the RCD keep tripping?

Accepted Answer

If the RCD trips constantly, it's often due to moisture entering outdoor lighting or appliances, or a faulty device. We recommend unplugging all equipment and trying to turn the breaker on again. If it still trips, contact us for troubleshooting.

Question 2

How much does it cost to install an RCD?

Accepted Answer

The price varies depending on your current electrical panel, but a standard installation usually costs between 2,500 and 4,000 SEK including the ROT deduction and materials.

Question 3

Is an RCD legally required?

Accepted Answer

In all newly built houses and during major renovations of the electrical system, an RCD is a requirement. Even in older houses, it is an extremely important and cheap life insurance that protects against personal injury and fires.

Question 4

What should I do in case of an electrical emergency or power outage?

Accepted Answer

Safety first! If your RCD (jordfelsbrytare) trips repeatedly or you smell burning plastic, do not touch anything. Smista Elinstallation offers fast assistance for emergency electrical faults in Greater Stockholm. We do not have a formal 24/7 emergency service, but we always try to help both new and existing customers every day and at all times of the year when an emergency occurs. Call us and we will assess the situation and dispatch a certified electrician as quickly as possible.

Question 5

Which electrical installations provide the biggest savings on my energy bill?

Accepted Answer

The fastest ways to lower your energy costs are installing smart home controls (like Plejd) and upgrading to energy-efficient LED lighting. By scheduling your heating and lighting according to spot electricity prices, you can reduce energy waste by up to 20%. We handle all types of electrical work, from smart homes to safe EV charger installations.

Question 6

Can I use the ROT deduction and Green Tech deduction at the same time?

Accepted Answer

Yes! When we install an EV charger, we apply the Green Technology deduction, giving you a 50% discount on both materials and labor directly on the invoice. For other general electrical work in your home (like upgrading a fuse board), we deduct 30% of the labor cost via the ROT deduction. We handle all the paperwork with the Swedish Tax Agency for you.

Question 7

Why is it important to hire a certified electrical company?

Accepted Answer

Faulty wiring is one of the leading causes of house fires. Smista Elinstallation AB is a fully authorized electrical contractor approved by the Swedish National Electrical Safety Board (Elsäkerhetsverket) with over 30 years of combined experience. This guarantees a safe installation, valid warranties, and the official documentation often required by your insurance company.
