Frequently Asked Questions – Electrical & Lighting

What type of work light should I use on site?

The best work light depends on the size and type of area you're illuminating. Portable work lights are useful when the light needs to be moved regularly, while tripod lights can provide broader illumination across larger working areas. Always check that the light is suitable for the environment in which it will be used.

Are LED work lights good for building sites?

LED work lights are widely used on building and renovation projects because they provide bright illumination while being energy efficient. Different sizes and designs are available depending on whether you need general area lighting or more focused task lighting.

What should I look for when buying a cable reel?

Consider the cable length, number and type of outlets, maximum electrical load and where the reel will be used. The connected equipment should remain within the manufacturer's stated electrical rating, and the reel should always be operated according to its instructions.

Should a cable reel be fully unwound before use?

Some cable reels need to be fully unwound when supplying higher electrical loads because heat can build up in coiled cable. Requirements vary between products, so always check the manufacturer's instructions and maximum ratings before use.

What is a site transformer used for?

A site transformer converts the incoming electrical supply to a different voltage for compatible equipment. On UK construction sites, transformers are commonly used to provide reduced-voltage power for suitable tools and equipment. Always make sure the transformer output and power rating match the equipment being connected.

What does 110V mean on site equipment?

110V refers to the operating voltage of compatible site tools and equipment. Reduced-voltage equipment is commonly used on UK construction sites as part of site electrical safety arrangements. Suitable transformers, connectors and equipment should be used together and in accordance with site requirements.

Can I use an extension lead outdoors?

Only use an extension lead outdoors if the product is designed and rated for the intended environment. Consider exposure to water, dust and potential damage, and always follow the manufacturer's safety instructions.

Can I plug power tools into an extension lead?

Power tools can be connected to a suitable extension lead or cable reel provided the equipment is compatible and the total electrical load remains within the extension lead's stated rating. Check the ratings of both the extension equipment and connected tools before use.
