I’ve got couple cheapie’s from harbor freight… I hardly ever work on 120/240V house current, only when need to common little jobs, but when I do I remove power and verify no power.
OK now we can hear rant about cheap HF junk from other posters?
I had all this heat shrink so I put it to use even on my socket extensions. Somebody talked about 1000Vs who would be working around 1000V that’s not professional linesman’s? When I works at Rock Quarry in my teens and early 20s the plant operated on 880Vs from big diesel power unit, with Hugh wires feed crusher plant running several conveyor belts to load out different size crushed rock material. there was no way they let new or inexperienced employees work on that.
I once was shocked (tingling) from lime (finely crushed rock/dust let over from hammer mill going up rubber conveyor belt touching metal in bin holding lime filling my truck. I told the Forman I was getting it shocked from rock when I stuck my fingers in lime going up belt into truck. I hadn’t touch any metal from bin holding rock.
He laughed and said can’t cause of rubber belt. Well guess what? The next guy backed up to conveyor and his truck beds grounded against conveyor frame. When he grabbed tail gate handle he was getting lots of stray volts, enough he couldn’t break free of handle. The Forman seen this and Done side body block and knocked him off handle. The 440V electric motor running conveyor belt had short due to recent rain.
