13 essential home electrical safety rules to follow

Generated by DALL·E

Electricity at home feels routine until the smallest mistake turns it into a hazard. A few disciplined habits make all the difference — and they take less effort than dealing with the aftermath.

Do not overload outlets and power strips

Risk: plugging a kettle, microwave and multicooker into one adapter is asking the circuit to do more than it can.

Do it right:

  • connect high‑power appliances to dedicated outlets;
  • use a power strip with ample load capacity.

Do not push furniture tight against outlets

Risk: overheating and hidden softening of plastic components.

Do it right: leave a 5–7 cm gap for airflow.

Never twist wires together

Risk: oxidation, heat buildup, and fire.

Do it right:

  • terminal blocks;
  • factory clamps;
  • soldering.

Match bulb wattage to the fixture

Risk: a 100 W bulb in a 60 W socket overheats the fixture body.

Do it right: use bulbs strictly within the stated rating.

Water heaters and washing machines — only with grounding

Risk: current leakage in a bathroom can be deadly.

Do it right:

  • ensure proper grounding is present;
  • install an RCD.

A warm or burnt‑smelling outlet is a warning

Risk: melting contacts.

Do it right:

  • switch off the breaker;
  • mark the circuit so it is not turned back on;
  • call an electrician.

Do not charge your phone on the bed or under a pillow

Risk: overheating and fire.

Do it right: charge on a hard surface with ventilation.

Check string lights and power adapters

Risk: cheap models may lack overheating protection.

Do it right: choose certified products and inspect the cables.

Do not repair high‑power appliances yourself

Risk: capacitors can retain a charge and shock even when unplugged.

Do it right: leave repairs to a professional.

Keep batteries away from sun and heaters

Risk: lithium‑ion cells can swell and rupture.

Do it right: store them in a cool, dry place.

In a short circuit, go to the breaker first

Risk: panic and random actions only escalate the problem.

Do it right:

  • switch off the breaker;
  • make sure there is no smoke;
  • then look for the fault.

Never plug into a loose outlet at an angle

Risk: arcing and melted contacts.

Do it right: replace the outlet.

The golden rule

If something gets hot, sparks, smells odd, or runs erratically — turn it off immediately. It is simply not worth the risk.
