)

90 0.

2. Set to Copper (if necessary):

(

Cu/Al

)

90 Cu 0.

3. Enter Wire Size:

*

AWG 2 CU WIRE SIZE

4. Find Resistance:

(

Wire Res

)

OHMS 0.2033993 WIRE

5. Find 85-foot Resistance**:



0.0172889

* Wire size can also be entered in Circular Mils (e.g.,



enters 10,380 CMILs and displays 10 AWG

Wire Size).

** Given Resistance per 1,000 Feet, divide by 1,000 to get a per

Foot Resistance, then multiply by 85.
