Now you can add a torque screwdriver to the many things you have seen ...like fire and rain, and sunny days you thought would never end...Davis9 said:

Thanks for the pic. I'm guessing the local supply house doesn't have that one.

Counter men want something they understand or a part number if they do not understand what you need they say "we do not stock that".

My (3/8") torque wrench reads in ft/lbs... so I convert to inch/lbs.
I torqued some main lugs yesterday.....GE meter Main and Square D Breaker panel.
GE spec. called for max 200 in/lb. so I torqued them at 16 ft/lb.
Square D (Homeline) called for max 250 in/lb. so they got 20 ft/lb.
How many of you carry a torque wrench (rated in in/lb.) that will go to 250?
I suppose the accuracy is better on a in/lb. wrench although torque is torque and if the wrench is calibrated, either should be OK.
How many torque the connections on branch circuit breakers, ground connections and receptacle and switch connections?
Just curious

You need a little more torque there don't you? Edited I now see the "max" part.
I've also noticed that most manufacturers include a Newton Meter value as well.
200/12=16.6
250/12=20.8
I haven't been able to find a receptacle torque value. I wanted to make sure the cordless driver provided enough torque.

It shouldn't be much of a problem to find one. Klein, SK and Wiha all make torque screwdrivers, along with many other companies. Here's a Klein
and here it is from Sears under the Craftsman name:

I got my Klein as a set from Sears:
These are for small torqe values, which is why I also have four torque wrenches in various sizes and ranges.

A very good dicussion of torque can be found in the article "Explanation of Torque" at
http://www.marathonsp.com/HTML%20PAGES/TechnicalInformation.htm
My old factory, we never calibrated anything for ten years plus. When we went to yearly calibration for all torque tools, etc., for ISO registration, we found that nearly every tool in the place (over 200) was out of specifcation.
