Electrical equipment: for Workshop, Site, Home and Garden

First define the job: compressed air, welding, water supply, cleaning, metal or wood processing, concrete work or power protection. Each type has its own key parameters: output, pressure, current or working dimensions. More: how to choose an air compressor and how to choose a water pump: types, flow and head.

Most household and semi-professional equipment runs on a 220–230 V single-phase supply, while powerful compressors, machines and welders may need 380–400 V three-phase power. Also check the starting current and the circuit breaker rating of your supply. See volt (V) and what is electric current (A).

Voltage fluctuations can damage motors and electronics, especially inverter welders, pumps and boilers. On an unstable supply, use a voltage stabilizer or UPS with a power margin. Read how to choose a transformer, power supply, voltage stabilizer, UPS and inverter.

For long continuous work, choose equipment with an induction or heavy-duty motor, thermal protection and a suitable insulation class. For welders and compressors, check the duty cycle. See what is motor thermal protection and what is insulation class.

For the garden, construction sites and damp areas the IP rating matters, and for pumps and pressure washers a residual current device too. Check whether the equipment is designed for outdoor use. Read what is an IP rating.

For powerful equipment, use an extension cord with a suitable cross-section and fully unwind the cable reel so the cable does not overheat. Check the cord and plug before work. See how to use an extension cord safely and how to inspect a power cord and plug.

Connect equipment to an earthed socket, never work with a damaged cable, disconnect the power before maintenance and use personal protective equipment. Read essential power tool safety rules.
