He should of teamed up with Lord Armstrong. Bit of an age difference , but who cares.Yeah...and used plenty of his genius ideas to their gain...
If only he'd gone to Manchester instead of NY.

Too true, with Tyneside manufacturing. I'm just thinking of the possibilities for industry around these parts but we could have been years ahead in all sorts of fields. Mind you, there were always money men to cut the futuristic down to size.He should of teamed up with Lord Armstrong. Bit of an age difference , but who cares.
That's what basically happened to Tesla. Armstrong was a bit more pragmatic.Too true, with Tyneside manufacturing.

How did you?as i came across the other week. meter monkey had sheared the head off one of the terminal screws on the meter Lout. was a right pain getting it out with the juice on.
We know a song about that don't we Johny.
1 side of the screw was left, but other side of slot gone. careful use of sidecutters to break lock, then screwed out with long-nose pliers.How did you?
Happy in the US in the 2020 NEC edition we have adopted that all that terminations be torqued to the manufacture ins-trucking and pass inspection by code enforcementI have been umming and arghing about a torque screwdriver for some time but have not yet bought one.
My fears are the following:
1. There are set torque settings that conductors in a consumer unit should adhere to. However, in the neutral bar which are screw terminals I tend to screw a 6mm in tighter than a 1mm (for example), as if you screw in a 1mm too tight it can shear. You can screw in a 6mm pretty much as tight as you can without fear of it going through the copper. I cant see how a torque screwdriver distinguishes between a 1mm and 6mm. Does it? Does it need to?
2. Are torque screwdrivers always accurate? If I use my normal screwdriver I have a 'fairly', if not 'very' precise feel for how tight I have made the connection. This experience will only improve over the years and you will make varying degrees of tightness as required. You lose this with a torque screwdriver and put all your trust in the mechanism.
I wonder if a torque screwdriver may not be a good option for someone who knows how to use a screwdriver properly? However, I am very much open to persuasion hence the post.
One last thing about this..
Do you have to send off your screwdriver to be calibrated or can you buy some sort of calibrating tool to do it yourself?
I guess send it of probably once a year I haven’t found one yetOne last thing about this..

I found one that they use to work on firearms and it’s the cheapest yetOr we could club together and buy one of these: Mecmesin | Torque screwdriver check calibrator - https://www.mecmesin.com/software-controlled-torque-systems/torque-screwdriver-check-calibrator I have no idea how much one would cost, but I assume it would not be cheap.
This is the problem with low torques, it is not so bad on new equipment, but a bit of crud on old fittings can influence a low torque.if CU designers were that fussy about torque settings, then they should at least make the terminals so that they didn't cam out before specified torque is reached.
