6.
The input wire gauge must be sized to accommodate the single-
phase input current, which will be approximately 1.8 times the
total three-phase output current to the load(s).
For example, if the
output load is 20 Hp, the three-phase output current will be
approximately 54 amps, and the single-phase input current will be 88
amps.
7. The maximum wire gauge for the input terminals is listed in Table 1.
8. Never allow bare wire to contact the metal surfaces.
9. Never connect AC main power to the output terminals T1, T2, and T3.
10. Input power to Phase Perfect
should be wired by a qualified electrician
into a 208V or 240 V circuit with adequate current carrying capacity
and the appropriate sized breaker.
Branch circuit protection to the
phase converter should be provided by either an appropriate size 2
pole, linked circuit breaker. Circuit breaker size for each model Phase
Perfect
is listed in Table 1.
