What Is a Temporary Builders Box?
A plain-language explanation of temporary builders boxes — what they are, what's inside and why pre-wired units save time on site.
Site power before the permanent supply
A temporary builders box provides power to a construction site before the permanent metering and switchboard are installed. It gives the trades protected GPOs for tools, lighting and site sheds, and connects to the network through a temporary service.
What's inside
A compliant builders box is a small switchboard purpose-built for site power.
- —Main switch to isolate the box.
- —RCDs or RCBOs on every socket circuit.
- —Single and three-phase GPOs as required.
- —Service fuse and neutral link on the supply side.
- —A weatherproof enclosure that closes over leads.
Why pre-wired
A pre-wired builders box arrives assembled, tagged and tested, which removes the most common inspection defects and gets the site powered fast. EVO supplies pre-wired builders boxes to the trade — request a quote with the site's power requirements.
