I've always wired plugs with equal-lengths to the terminals.
So if the cord-grip fails the resultant tension is then equally-distributed between the 2 or 3 conductors/terminals - reducing the ongoing risk of any conductor being partially-pulled from its terminal and causing continuity-failure (which is distinctly annoying when you have an uptime contract to comply with) or any sort of arc/meltdown.
Having had a few thousand bits of kit annually-inspected for PAT-compliance reasons over a couple of decades, I honestly don't recall cord-grip-failure being a reporting issue! |
Surely equal lengths to the terminals only works if the terminals are laid out for equal length wires.
Normal best practice is to cut the wires to such lengths that the line and neutral wires follow paths with equal amounts of "slack" and the earth wire has additional "slack" so that in the event of a cable pullout the earth lets go last.
