• ### What does electrical wire sizes in mm mean?

• Electrical wire sizes in mm (millimetres)can either mean the diameter of the wires or the cross-section area of the wires. Allow me to say that throughout this talk, I will be referring to the cross-section area of the wires in millimetres. In the following paragraphs, you will know electrical wire sizes in mm and uses.

• ### How do you calculate wire size from standard?

• In order to calculate the wire size, substitute the values in the formula as follows: The standards used are, D0 = 0 005, r = 0.46 0.005 = 92 and d = -3. Dn = 0.005 in. 92 ( ( 36 鈥?n) 39) Dn = 0.127 mm 92 ( ( 36 鈥?n) 39) n = -39 log 92 (Dn 0.005 inch) + 36 = -39log 92 (Dn 0.127 mm) + 36.

• ### What size wire do I need for a lighting circuit?
