Question

All electrical wires should clear flat roofs by _______.

Answer 1

All electrical wires should clear eight for flat roofs and 12 for driveways. A complete electrical circuit must have a path, load, and voltage. Two wire service will only have 115V. Voltage itself is the measure of the driving force that drives the electricity in an electrical wire. Electricity in itself can be sold in quantities of kilowatt per hour.
