WARNING:
Above wiring and breakers rates are only a suggestion. The wire size is strongly affected by diverse factors such as: Operation
temperature, wire length, type of wire, quantity of conductors and kind of installation. Electrical contractor must assure an
appropriate selection for wire and protection devices sizing for complying with local regulations for electrical installations. Wiring
colors must be selected according to local directives and regulations
