Some folk wouold scoff at the fuses and protection on that 28V system, but those busbars were fed from one heck of a big battery bank. The short-circuit current would have been well into the four-digit range, possibly even five.

I've heard stories about wedding rings and car batteries. That one needs to remove the ring before working with such batteries. Else you could literally burn your finger off from the heat of the fault current thru the ring from +12V to ground.... [Linked Image]

Once had a boss who had an ivory wedding ring (non-conductive material) to avoid this hazard, as well as any wayward smaller hot wires accidently getting under the ring to make a "good" connection to his body for a shocking experience. [Linked Image]
