“the manufacturer will usually spec a minimum size but it doesn't always hold uh hold to the letter because uh if you're in a scenario where you've got to run cable a long distance it's possible that the even the minimum size cable that the manufacturer is recommended uh won't be big enough again it comes down to distance”
