Powerupgrade
Intro
Electrical power at techinc was done with very limited resources and funds (practically zer0) that we had at the time. Now we're reaching the point where those limitations are becoming increasingly evident. A number of people have expressed their desire for a substantially larger feed than the 3 x 13A/16A we have now. As such the Powergroup has undertaken the planning to upgrade the power supply and distribution to the space.
What?
Install a 5x 6mm² cable between the UR power cabinet down stairs to the Fusebox in the dirty room, then distribute this to various circuits round the space, replacing the separate UR provided power circuits such as the one in Maker lane, most of the power in Main space, and the network rack.
How?
A 5x6mm2 cable was pulled along the existing lower capacity cable. Soon an electrician can connect the cable, while upgrading the 3 16A fuses downstairs. The fuses downstairs can be upgraded to 3 x 50A slow (parts already purchased). The new fusebox is a ABB Mistral IP65 3 x 18 box. It will have a main switch (4 wire simple switch 40A already found), fuse 1P+N on each phase (40A B=fast profile) after which the various phases and groups are split out. We try to use an 'alamat' (16A switch + 30ma ground breaker in 1 unit width) on each simple group, although those are quite expensive (5 euro from ali express uncertified... or 27 euro Kema Keur). We leave room for various DIN power meters on specific groups like server room, but also on the main phases.
Groups
The following groups should be made in a new fusebox:
- makerlane
- radiolane
- main hacktable + fireplace
- solderlane
- main powerbar
- aux powerbar
- hardware ('dirty') room (possibly 2 x)
- 2 x serverroom (redundancy)
- dishwasher + waterheater
- kitchen fixed equipment (microwaves, fridges, cofvevemaker)
- 2 x kitchen open sockets (water cooker, covfefemaker, electric pans, toasters)
- cooking group (2 or 3 phase) for builtin induction cooking stove (as soon as we install that)
- 3-phase 16A socket hardware room
- optional: 3-phase 32A socket hardware room
This adds up to:
- 14 simple 16A groups
- 3 3-phase groups
