I’m wondering if this comes with a wiring diagram. We will be deploying one of these for every two server cabinets in a server farm. As this is a 4 pole isolator it is likely that there are a number of terminals (L1-L3 on top and T1-T3 on the bottom with earth terminals present too). Each of these isolators with be connected to a double gang standard (U.K) plug socket with a fused PSU (one power supply unit running the equipment in each server cabinet). The supply to the isolator will be single phase 2.5mm Twin and Earth. Can you please specify when using 2.5mm Twin and Earth for the load and supply which terminal are for live, neutral and earth? Many thanks in advance.

Hello Lee, unfortunately there is no wiring diagram available from the manufacturer. However we have added an image of the terminals to the product listing at: https://www.electricalworld.com/en/KnightsBridge-32A-4-Pole-230V-415V-IP65-Industrial-Rotary-Isolator/m-1858.aspx - the manufacturer has provided us with wiring instructions as follows: The top side is the Mains in and the bottom is the Load side. To wire it up, you will connect your mains Live wire to either L1, L2, or L3, depending on need and your load Live to T1, T2, and T3, depending on need. If you wish to have the Neutral switched as well, connect it via the Neutral terminals next to the Lives. If you don't need a switched Neutral you can use the terminals seen on the left in the image. Connect the earth wires to the Earth terminals seen on the right in the image.
