Note to all here, please take the fact of the holdiay season to forgive me of my sin, I have been in the habit of taping over the exposed terminals on switches that are connected to 277 volt lighting circuits for many a year. Somebody just might not have gotten a blast out of me. Knew it wasn't required.

safety is never a waste of time

safety is never a waste of time

I always tape,have for 28 years,your fingers ever get shaky? ever not been able to shut down circuit? well good for you, I'll continue to tape thank you
 
So, Before you tape the wire nut, do you twist the wires?
Does it matter if you tape the device and the ground is up?
Does the tape have to be scotch 33?
Since when has an engineer/architecht had the time to see if you tape devices?

Just asking incase I run into one of these "ANAL" folks.I want to be prepared.

Set screw/compresion, no dif. Most are in such a hurry to hack it in neither gets tight. Hence the EGC.

I chalenge anyone to give one (1) example of a resi ckt that can't be shutdown. Medical. They all have battery back up. I know.

For coomercial/industrial, You don't think that when your a@@ gets blown up and your on the floor quivering like a flounder on mercury, that the production won't some how recover?

Heros get bridges named after them. But they never know it.

It is a personal thing. I mostly would not tape but have. IMO it is kinda of like wearing a belt with suspenders, especially in plastic boxes.

ground up ground down
tape wire nuts
tape switches receptacles
What else?

You're right. I only wear a belt with suspenders in metal boxes. :grin:

Right here.
Think about this... Not all tapes are created equal. 33, 88, Super 10, Scotch 22 all have excellent fire retardant abilities, but pay attention to what type of tape you use. The terminations on devices have certain temperature ratings, and wrapping with an electrical tape that doesn't have at a minimum that tamp rating would be trouble, I would think. UL 510 addresses flammability ratings for electrical tape. There are some that would not be suitable for wrapping receptacles due to their temperature rating alone, so it would seem. That's all you'd want to do is wrap a receptacle with "fuel". Some have adhesives that are corrosive to metals and so forth. Vinyl versus rubber electrical tapes differ considerably in there fire retardant ratings. Pay attention to the tape you use, and don't just pick any old tape to wrap your devices.

Took the words right out of my mouth..:smile:

I won't say I never have but I hardly ever do.,..Sometimes in the kitchen when the home owner isn't sure if the back wall over the counter is getting tile or not. ..I have a feeling the tile guys don't bother with shutting circuits off

If you know you get shaky fingers maybe pulling out hot devices is just a bad idea to start with?




That was this mornings verse from the 'Don't work live' Chorus. :wink:

You could leave the band at home and could use this:

The blades usually provide a snug fit for device removal....

..or you could get the "D-luxe" homeowner version:
