Recommended Cable Sizes

WARNING: At 100% switch mode load, the neutral must be rated for 200% phase current.

Caution: All wiring must comply with all applicable national and/or electrical code.

Note: The recommended cable sizes are based on an environment with an ambient temperature of 30° C (86° F). Use stranded copper cables.
