12 2.4 Electrical safety
- Avoid overloading: do not plug several high-power appliances into one socket; the large current can overheat the wires and cause a fire.
- Insulation: wires must be properly insulated so that you cannot get a shock.
- Dryness: make sure hands, wires and components are dry; tap water conducts electricity.
- Disconnect the source before changing anything in a circuit.
- Never use household mains in school experiments; use batteries.
