Requirements for the conductors:
☐ The conductors with regards to its ampacity, rated temperatures, operating conditions and its
power loss must be made in accordance with the local standards and the National Electrical
®
Code ANSI/NFPA 70 or the Canadian Electrical Code
☐ Conductor cross-section: 0.2 mm² to 2.5 mm² (24 AWG to 14 AWG)
☐ The conductor type and wiring method must be appropriate for the application and location.
Procedure:
