Electrical Safety

The device shown is a

• RCD

• Transformer

• Proving Unit

• Storage Battery

The correct voltage to use on a construction site is

• 110 Volts

• 230 Volts

• 400 Volts

• 12 Volts

How often should electrical tools be PAT tested when they are used on building sites

• every 1 month

• every 3 months

• every 6 months

• every 12 months

A visual inspection should be carried out on electrical tools

• at least once every week

• at least once every month

• at least once every 3 months

• every time before it is used

the device identified is a

• multi meter

• proving unit

• voltage indicator

• transformer

The device shown is a

• voltage indicator

• proving unit

• multi meter

• transformer

The symbol shown means that the appliance

• needs an earth connection

• does not need an earth connection

• is safe to use

• operates at 110 Volts

the symbol shown means that the appliance

• needs an earth connection

• does not need an earth connection

• is double insulated

• needs to operate at 110 volts

the correct colour coding for the wiring of a plug would be

• earth green and yellow / blue line / brown neutral

• earth green and yellow / blue neutral / brown line

• earth blue / neutral green and yellow / brown line

• earth brown / neutral blue / line green and yellow

to convert from 230 Volts to 110 Volts you would need a

• step up transformer

• step down transformer

• a 230 Volt generator

• a 110 Volt generator
