Question 1

When is it urgent to book an electrical troubleshooting service?

Accepted Answer

Act immediately if your RCD (jordfelsbrytare) trips repeatedly, fuses blow constantly, you smell burning plastic near outlets, or you hear crackling from the electrical panel. These are warning signs of serious loose connections or short circuits that could cause an electrical fire.

Question 2

How does a professional electrical troubleshooting work?

Accepted Answer

Our certified electricians use advanced diagnostic tools to systematically isolate and identify the fault. We typically start at the electrical panel to determine which circuit is affected, then measure through cables and outlets until we pinpoint the exact source of the problem safely and efficiently.

Question 3

Why does my RCD trip when it rains?

Accepted Answer

This is most likely due to moisture penetrating your outdoor lighting, engine block heater outlets, or damaged exterior cables. The RCD protects you by cutting the power at the slightest leakage. Contact us, and we will replace the moisture-damaged components with weather-resistant alternatives.

Question 4

How much does emergency troubleshooting cost?

Accepted Answer

We charge an hourly rate for troubleshooting, and most faults are located and resolved within the first or second hour. Naturally, you receive a 30% ROT tax deduction on the labor cost. Once the fault is found, we always provide a fixed price for the permanent repair before proceeding.

Question 5

My lights are flickering strangely, is it dangerous?

Accepted Answer

Flickering lights can indicate voltage drops, a faulty dimmer, or an overloaded phase in your home. If the issue occurs throughout the entire house, it is serious and could point to a fault in the main incoming power supply. An authorized electrician should inspect this immediately.

Question 6

Am I allowed to troubleshoot and replace wall outlets myself?

Accepted Answer

According to Swedish law, you are allowed to replace an existing wall outlet (max 16A) if you have the necessary knowledge. However, you must never make new installations or troubleshoot the fixed wiring behind the outlet. If you are unsure why a fuse is blowing, it is always safest—and legally required—to hire an authorized electrical contractor.

Question 7

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. We offer 24/7 emergency electrical services across Greater Stockholm with fast response times. Our certified electricians will secure your electrical system and fix the fault immediately to minimize the risk of fire or property damage.

Question 8

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 9

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 10

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.
