Project/ElectricalWorks/MainRoomRefit
Introduction
A project to cover the electrical works in the Main Room refit.
Clear the west wall, install a plywood skin, then install four work stations with power and data.
Objectives :
- Replace the existing West Wall mounted sockets with sockets in dado trunking on the new wall.
- Move the circuit feed onto the kitchen distribution board
- Maintain power for the heat pump
- Integrate power and controls for the extractor fan
- Provide capacity for the 3d-printer stand at a future date
- Install new data wiring
Current State
The existing sockets are connected to a 32A ring main, wired back to the Main Board.
The extractor fan is connected via a switch-fused connection unit, which then feeds a separate speed controller and out to the fan itself.
A 20A circuit from DB2 connects to an isolator for the heat pump.
Planned Work
- Test the circuit is not feeding the Server Rack in the cupboard.
- Identify cable route from ceiling into back of new plywood wall
- Arrange temporary power for the Design PC's and 3d printers. Need 8 sockets. 2 x 4-gang leads from Electronics benches ?
- Disconnect the existing sockets and data cabling, and remove back to the Main Board.
- Disconnect and remove the extractor fan wiring. Install extra cable to the fan to allow for fitting behind the plywood wall and into the dado trunking
- Pull through new 4mm T&E cable between the Kitchen Board and the Main Room for the new ring circuit.
- Pull through 8 x data cables for new network sockets in dado trunking.
- Install new dado trunking, and fit sockets and data points.
