Hello,
I have a question regarding the construction site power distribution box and whether anyone has experience with how it is allowed to be installed. The white power box from the utility company, where the temporary site power distributors are usually connected, is located about 100m (330 feet) away.
My question is, how far away from the supply point can the distributor be installed? The reason I ask is based on the experience at my brother’s construction site two years ago. The distributor was connected right next to the supply point, which meant running 80 to 90 meters (260 to 295 feet) of cable. At 230V, this was still manageable though inconvenient. However, with a 380V cable of 30mm² (about 0.047 in²) cross-section, it becomes much more difficult.
Ideally, the box would be placed directly at the construction site. My only question is whether that can be arranged.

So just go ahead of the RCD, and that’s fine.
Two RCDs are now mandatory anyway – separating lighting and power, I read this only recently and think it’s very smart.
