Intro
Electrical power at techinc was initially done with very limited resources and funds (practically zer0) that we had at the time. After some years we had reached the point where those limitations were becoming increasingly evident. A number of people then expressed their desire for a substantially larger feed than the 3 x 13A/16A there was. As such the Powergroup has undertaken the upgrade to the power supply and distribution to the space. This is mostly implemented by now.
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. An electrician has connected the cable, while upgrading the 3 16A fuses downstairs. The fuses downstairs were upgraded to 3 x 35A slow. The new fusebox is a ABB Mistral IP65 3 x 18 box. It has a main switch (4 wire simple switch 40A), fuse 1P(+N not connected) on each phase (40A B=fast profile) after which the various phases and groups are split out. There is an earth protection (aardlekschakelaar) on phases L1 and L2 with 4 groups; two on L3, giving a total of 14 single groups. There are also 2 3-phase groups with builtin earth protection ('alamat') for cooking, and for the dirtyroom 3-phase socket.
There is also a 3-phase power meter with LCD display installed (suitable up to 3 x 80A). It has a pulse interface for measuring power usage (1 pulse per watt). See https://www.eltako.com/fileadmin/downloads/de/datenblatt/Datenblatt_DSZ15D-3x80A.pdf and https://www.eltako.com/fileadmin/downloads/de/_bedienung/DSZ15D-3x80A_28380015-1_dt.pdf
The last group is used for a WCD in the case (normally not used, only for maintenance purposes), and powering a 5V 2A DIN PSU which powers a raspbery Pi Zero-WH. The intention is to run something like http://ondrej1024.github.io/emond/ on it to measure power usage, both on local display and on some part of the space state API and/or MQTT.
Groups
The following groups have been made in the new fusebox:
- hardware ('dirty') room
- kitchen fixed equipment (dishwasher + waterheater)
- kitchen fixed equipment (microwaves, fridges, cofvevemaker)
- 2 x kitchen open sockets (water cooker, covfefemaker, electric pans, toasters)
- cooking group (3 phase) for builtin induction cooking stove
- 3-phase 16A socket hardware room
- 2 x serverroom (redundancy)
- main powerbar
- aux powerbar
- radiolane
The following still need install:
- makerlane
- main hacktable + fireplace
- solderlane
This adds up to:
- 13 simple 16A groups
- 2 3-phase 16A groups
