Revision as of 17:00, 2 April 2013
Power General Notes:
- Existing 230V/13A wall sockets should only be used for low-current equipment, not large items. The latter will have a separate supply
- New circuits will be installed with local distribution boxes so that there should never be a need to access the main electrical intake room (which belongs to the landlord, not us)
- Re safety emergency buttons (eg. RS 330-8559) they can be fitted per item of equipment or per room. There is a strong argument that if someone away from the area where the emergency occurs runs to offer help they don't want to have to work out which kit is the problem, and that therefore the room power should be killed as a 'safety-first' issue. Latest discussions are that there will be a 'room' one external to the new workshop rooms, with some 'item' ones inside. Further comments welcome.
- Maintained emergency exit signs will be located as per plan (at least). There are already emergency lights in place covering the whole floor which have been tested.
- If in doubt, talk to User:AlisonW. If you need something special in your area, talk to User:AlisonW. If you think this is wrong, talk to User:AlisonW!
Basement
Existing lighting remains in situ, along with some wall sockets (mostly at main stairs end). New circuits will be provisioned via new distribution boxes as follows:
Box A: All power, except overhead lighting circuits, which is used in the wood workshop. Individual circuits for major equipment plus one 'general sockets'. As appropriate, mushroom STOP buttons to be installed for dangerous equipment (User:Solexious is co-ordinating)
Box B: All power, except overhead lighting circuits, which is used in the metal workshop. Individual circuits for major equipment plus one 'general sockets'. As appropriate, mushroom STOP buttons to be installed on dangerous equipment. (User:Solexious is co-ordinating)
Box C: All power, except overhead lighting circuits, which is used in the biolab and wet room (darkroom). Biolab circuits per their request.
Box D: Power circuits, except overhead lighting, for equipment in general workshop area. Major equipment (eg. lathes) on individual circuits, with mushroom STOP buttons at point nearest central gangway or on wall (tbc). (User:Solexious co-ordinating)
Box E: 3-phase 16A power circuit. Not in current use,
Box F: Power for server stack, future CNC workshop, and additional circuits.
Ground Floor
This will be similar to downstairs in terms of getting the power to needed areas, though there are more socket points already in situ; New local distribution boxes are as follows:
Box J: Supplies sockets in local work area and (part of) central area. Also supplies emergency exit lighting above stairs and at main entrance.
Box K: Supplies sockets and equipment in local area (probably electronics lab) and circuit to outside (via separate local RCD).
Box L: Supplies the two socket rings in the new classroom, plus (part of) central area. Also supplies emergency exit lighting at each end of corridor.
