220v electric furnace hook up. for a furnace. I have installed a 220v electric furnace but have not finished the wire hook up and need some help.

Electrical Wiring Question I noticed a few web sites warned about not getting nicks in the wires as your stripping them.

Electrical Tip
The Safest Way to Test Electrical Devices and Identify Electric Wiring!
The Non-Contact Electrical Tester
This is a testing tool that I have had in my personal electrical tool pouch for years, and is the first test tool I grab to help identify electrical wiring. It is a Non-contact tester, [amazon.com], I use for the detection of Standard Voltage in Cables, Cords, Circuit Breakers, Lighting Fixtures, Switches, Outlets and Wires. Simply insert the end of the tester into an outlet, lamp socket, or hold the end of the tester against the wire you wish to test. Very handy and easy to use. |
