Notes:
• Wire size shown is based on maximum terminal size. Please consult the NEC or local codes for proper size to
be used.
• The wire size assumes a maximum voltage drop of 2%. If this value is exceeded, a larger diameter wire size may
be needed.
• Use only copper wires. Proper diameter wire should be based on ratings at 75°C.
• For safety reasons do not use under sized wiring.
