Overview
- Electrical Safety First notes many household extension leads are rated to 13A or about 3,000W, and running multiple large appliances can exceed that limit and cause overheating or fires.
- Kettles, microwaves, air fryers, heaters and toasters are singled out as too power‑hungry for extension leads and should be connected straight to a wall outlet.
- Heaters are highlighted as a particular winter risk because they draw high current for extended periods, raising the chance of overheating if used on a lead.
- Users are advised not to chain extension cords or power strips, to keep leads uncovered for airflow, to use only products rated for the environment and to stop using any lead that shows damage.
- Experts emphasize extension leads are a temporary solution, recommending a qualified electrician install a dedicated supply for long‑term needs, while low‑draw items like phone chargers and lamps are typically safe.
