Project: Workshop Power
This project is to install 3 phase power in the workshop area of the Hackspace, to replace the use of a temporary flexible cable which can only feed one item at a time.
We already have the Bridgeport Mill and a Donkey Saw which require 3phase power, but with the installation of proper infrastructure we will be able to run more powerful welders (TIG and Arc), and other tools we may get in the future.
We also need 3phase to run a motor / fan that we have for dust extraction. In addition to 3phase power, some higher-current single phase outlets are needed for welding equipment that we have. Including these in the project will reduce the reliance on 'domestic' 13A sockets for these items.
Key Dates:
Creation of project page 21st August 2013

Project Contacts
- David Clarke (Page creation, general guidance as to project direction)
- Matt Lloyd (interest in metalworking area tooling, and installation of the wiring)
- User:some_third_person
Other Stuff
Power requirements of tools we have
Bridgeport Mill (16A / 3phase)
TIG welder (70A / Single phase 415V)
Extraction fan motor
Power requirement of tools we might get
Length of supply cable
30 metres from the main switch area (cupboard in the Blue Room) along the South wall to the Workshop area. (N.B. needs checking, as this cable is available cut to the metre length)
Outlets required
16A/3 for Bridgeport 16A/3 for Donkey Saw Direct wiring to distribution board for TIG welder 32A/2 for Arc welder (guess, but we have these connectors already from Bridgeport) 16A/3 for Dust fan 16A/1 for MIG welder
Other stuff
We have a quantity of donated cable, which was originally used to connect the 16A/3 socket outlets that we have. As this is 'old colours' it is probably best to scrap this (could get £90) and use the money to fund the purchase of modern multicore flexible for the socket wiring around the workshop.
Costings
Distribution board and MCBs - Donated, though we may need some different MCBs 3phase 16A socket outlets - Donated, though these are non-switched. Otherwise £20 each, or £10 to add switches. 30 metres of 10mm² SWA 4-core cable + glands £130 Single-phase 16A socket outlets from £7 (http://chaloncomponents.co.uk/shop/article_GW62477/GW62477.html) Single-phase RCCDOs we have.
Some photos perhaps? Awaiting these.
