Just an off-the-cuff question.
How many of you guys that work with large current supplies, actually bother to do, or even have the test gear to do a true Fault-Current Assessment at the Mains Entry point, like at a Main Panel and the like?.
Your fusing and other protection equipment is based upon this figure.
And it is measured not in Amps, but Kilo-Amps.
This roughly will also give you the size of explosion that you can expect, should you Short circuit a Phase to Ground or from Phase to Phase.
There is a lot of test gear around these days that will do this for you automatically.
Fault currents are the single biggest killer, as in terms of serious burns recieved, next to direct contact with a live Phase.
Please, let's try and minimise the risk out there, guys!. [Linked Image]
