I've used heat shrink but someone brought up a very important point on one of the other fprums a while back.
Most of us focus on the fact that the ambient heat from the fixure is what we're trying to deal with but forget that the copper is not only a good conductor of electricity but also heat. As such one should not ignore the fact that heat is being conducted by the copper potentially beyond the box itself. So what about the insulation just outside the box?
I realize that this may or maynot be a problem and some might consider it to be spitting hares but can it be confirmed that the insulation temperature wouldn't be exceeded outside the box itself?
And, yes, I do carry heat shrink tubing in my took box with a heat gun. But are we making an informed decission when we repair or reinsulate the wires?
This is something that I never thought of at first.
