Electric

Portable electrical equipment Tools, plugs and cables designed for DIY and domestic use are not suitable for site conditions. You should use cordless tools or those that operate from a 110V centre tapped to earth (CTE) supply system so that the maximum voltage to earth does not exceed 55V.

By definition, a transformer is a static electrical device that transforms electric energy from one level to another level. Normally transformers are used to step up or step-down voltage and current levels, impendence matching and providing electrical isolation.

All electrical products have a data plate with information regarding their power usage. For most power tools (drills, sanders etc), their listed wattage is all the power they require to run. Household items such as central heating pumps, lights, TVs, video recorders etc. fall in the same category. Items such as freezers, fridges, washing machines, and some lawnmowers are normally different, whilst they can state a wattage rating, due to the type of motor they use can require a much greater requirement on start-up, when started they then require a smaller usage.

Running home computers from a standard generator is not advisable. You will need a generator that utilises AVR (Automatic Voltage Regulation) such as the Briggs Pro Max 6000A or an Inverter generator such as the Honda EU & EM Range. These generators will give you more stable electricity than the mains. Please note: As a generator runs out of fuel, the engine is likely to surge.
