whenever I use mains power on a PCB (or proto-board) I always remove the copper around the area but I am always wary of the juice just inches from my fingers while I am tweaking things and then when it is finished and working. Here's a tip I picked up watching a guy build a full-size A10 flight sim cockpit (this is worth a watch to see his entire process for producing excellent front panels). He was doing it for tidiness but I have used the same method here to insulate the back of a load of mains screw terminal and their associated mains wiring. Get a roll of sticky-back vinyl. Most craft stores will stock it, this roll was £4.50 from the Range here in UK.  Cut a couple of pieces to size, apply each and press down then go over it with a heat gun at about 150C and press down firmly again (I do it in about 1 inch sections), this softens and shrinks the vinyl so the wrinkles all get pulled out and the stuff will conform to any shape. The results of two layers of vinyl really builds your confidence that no-one should get a belt off your no-longer exposed mains terminals.  hth Edited 2019-09-10 18:51 by CaptainBoing |

Is this the kind of stuff you cover books with? Cheers Caveman Mark Off grid eastern Melb |

Possibly. It's adhesive vinyl film. Gathering from where I got it, it could easily be the same stuff as you mention. |
