ANSI/NFPA 70 or the Canadian Electrical Code® CSA C22.1. Operating
ambient temperature and humidity must be factored and considered when
selecting OCPD for the inverter output.
3.4.3.1 Aluminum Cable Requirements
When Aluminum cable is selected, use copper to aluminum adapter terminal to avoid direct
contact between the copper bar and the aluminum cable. Direct contact between the copper
bar and aluminum cable will cause electro mechanical corrosion and impair the reliability of
the electrical connection. When using aluminum/copper wire rated lug, no additional adapters
are required.
