It can be a size bigger or smaller than other wires. For very large wire sizes (fatter than 4/0), the wire gauge system is typically abandoned for cross-sectional area measurement in thousands of circular mils (MCM), borrowing the old Roman numeral "M" to denote a multiple of "thousand" in front of "CM" for "circular mils." What size ground wire do I need for 500 kcmil aluminum wire? Instead, youll want to plug into a power source. TriangleTM credit cards are issued by Canadian Tire Bank. So when your needing a three conductor cable to wire up a basic 2-way switch, you will need a 14/2 w/ground cable. Its a fastener that allows you to connect copper wire tightly to the grounding rod.
