Wiring Requirements 
ATTENTION
Safety First!
Be sure to disconnect the power cord before installing and/or 
wiring your IMC
-21GA. 
Calculate the maximum possible current 
allowed in each power 
wire and 
common wire. Observe all electric
al codes dictating the 
maximum current allow
ed for each wire size. 
If the current goes above the maximum rating, the wir
es could 
overheat, causing serious damage to your equipment.
