Quite possible.  Another possibility is the physical construction
of some equipment.  I've worked on devices that had very heavy
buss bars with tapped holes for lugged wires and plain holes to bolt
LARGE capacitors to.  The buss bars were often a couple of feet
long and looked like "rails" of metal.  But again, these buss bars
or rails were supply voltage conductors or a ground buss.
