Answers:
Use the appropriate terminals depending on the current requirement. Use of bigger terminals where the current is less increases the total cost of the product.
~Amarpal Singh Oberoi O, Research & Development, PUNE, INDIA
Ensure the purchase made is correct for all circuit conditions in use. When connecting terminations use the manufacturer's recommended torque settings.
~Dave G, Engineer, Falmouth Cornwall, UK
Use the proper size screw driver to avoid breaking the terminals and proper tightening torque.
~Fred D, Design Engineer, Pictou, Canada
Make sure they are rated for the correct voltage and SCCR when using in power circuits.
~Quality Control, KITCHENER, Canada
Use spring cage where ever possible - terminations don't come loose.
~Geoff H, Builder/Contractor, Warkworth, New Zealand
Measure twice, buy once Check the material rating carefully
~Larry K, Faculty/Staff, Amherst, MA
Terminals must be strong for quickly mounting cables.
~Martin Novak, Design Engineer, Brno, Czech republic
Shure, we suggest them how to use it on proper way.
~Jozef M, General Management, Maribor, Slovenia
Pull on the wire when you think it is clamped
~Other, Baton Rouge, LA
NA current is the problem
~Isay G, Reliability Lab supervisor, Bber Sheva, Israel
Test them at max torque
~Bob E., Purchaser, Bridgeview, IL
