Wire Sizing
Use
Table 7 to find minimum guidelines in properly sizing input and output conductors
according to local electrical code. The voltage drop from the supply to the converter should
be limited to 3% to ensure proper starting and operation of motor loads. Increase the wire
gauge to provide adequate voltage to the load. Ensure the wire gauge is suitable to the
terminal block.
Use the following formula to calculate line voltage drop.

Connecting the Load
Do not connect single phase loads to the manufactured leg, T3. This places unnecessary
load on the phase converter and may violate electrical code in some areas. Apply overload
and short circuit protection to protect load side conductors, motors and other attached
loads according to local electrical code. For some motor loads and wiring configurations
load side short circuit protection may not be required. Consult local electrical code for
guidance.
