Not all locations are as strict as BC, and below 50V (DC as well?) can
cause fires, etc. -- those pesky Li battery issues that you may recall.
My reference to power supplies was to all power supplies that have a
risk of "high" temperature, fire, or explosion.

In the Province of British Columbia, AC-side electrical equipment
is designed by registered Professional Engineers (PE) and worked
on by licensed electricians. At TRIUMF these people are better
than average.
Equipment we have built for SNOLAB and CERN was certified
by an outside licensed
A proper circuit breaker, hopefully with external or simple panel
removal access (not remove from rack, open chassis, remove ... ), will
work fine and typically is better than a fuse. A "soldered in place"
fusible link also will work, but is much more difficult to service and
replace. Anyone

you will not be amused to learn how many electronics
One SSD had an internal short and turned into a space heater, luckily
there was no fire. End excerpt.
Clearly, there is very poor safety engineering and/or quality control
(as with certain Li batteries that did similar things in personal
devices being operated by the user). If that SSD had
Hi, Larry, thank you for this information, it is always good to see
how other people do things.
I am surprised at how little storage you have, only a handful of TBs.
Here, for each experiment data acquisition station, we now configure
2x1TB SSD for os, home dirs, apps, etc and 2x8-10-12TB HDD
There are 25 systems in our shop, all linux based, a linux based server,
and synology Disk Station running raid 1. The Disk Station has 12 TB
of space. 6 TB per for each raid level.
We buy only one brand of disk with the black label. They are typically
1 TB.
User boxes has a SSD drive for
