Because site work runs on 110V centre-tapped supply rather than 230V. The transformer converts the supply, and its kVA rating sets how many tools it will run at once.

On the combined draw of the tools running together rather than the largest one. The range runs 1.5kVA for a single tool up to 10kVA single phase for several outlets.

Yellow is 110V and blue is 230V. That is a standard convention on site, so the colour identifies the supply before the rating on the plug is read.

No. The plug on the tool determines which outlet is needed, and a 32A plug will not enter a 16A socket. Both are held in 110V and 230V forms.

With a 3-way adaptor at 16A, which takes one outlet to three. The combined draw still has to sit within what the transformer supplies.

An RCD safety adaptor adds protection at the 230V supply point, which covers a socket that does not have it built in. Site lighting is also held on this leaf.

A site transformer converts 230V to 110V because 110V centre-tapped supply is what site work runs on. The rating in kVA sets how many tools it will supply at once, and it has to cover their combined draw rather than the largest one. A transformer that is undersized runs hot and drops voltage, which shows as a tool that lacks power.

The range runs 1.5kVA, 3kVA, 3.3kVA, 5kVA and 10kVA. A 1.5kVA transformer runs a single tool. A 10kVA single phase unit supplies several outlets, and the vented 5kVA form handles sustained loading where a sealed unit would heat up. Vented forms shed heat where a sealed body would need derating on a long shift.

Connector amperage is stated separately and has to match the tools. 16A and 32A outlets are not interchangeable, and the plug on the tool determines which is needed rather than the transformer capacity. Colour identifies the voltage: yellow is 110V and blue is 230V. Draper Defender Power Pod transformers at 3kVA and 3.3kVA sit alongside the Sealey WST ladder. A tool bought with a 32A plug cannot be run from a 16A outlet without changing the plug, which is not always permitted on site.

Adaptors and protection complete the setup. A 3-way adaptor takes one outlet to three, and an RCD safety adaptor adds protection on a 230V supply where none exists at the socket.
