Project/ElectricalWorks
Introduction
A page to track the electrical changes requested and made in rLab.
Any works carried out on the building electrical supply MUST be completed in accordance with the current version of the IET Requirements For Electrical Installations (the Electrical Regs) and by people who know what they are doing. This is one area where we do not simply 'hack the space' as the consequences of getting it wrong are too severe.
As data cabling often overlaps with the electrical installation, sharing trunking etc, it is also covered on this page.
If you have any projects that may need changes to the lab electrical system, please ask before you go ahead with the project. Anything unsafe will be removed without notice.
