The PD66 and PD620 are designed for use on Three Phase (3Ø) WYE 120/
208V 4-pole 5-wire electrical service. With the ability to operate on Single
Phase (1Ø) 120/240V 3-pole 4-wire electrical service, (easily configured
internally).
DO NOT connect high voltage leg of DELTA type systems (the higher voltage
will damage sensitive equipment connected this way)—see NOTE below.
The
PD66
can provide up to 140 amps total, 40 amps on one leg, 50 amps
each on remaining two legs (3Ø WYE 120/208V hook-up),
OR
*70 amps per
leg (two legs) (1Ø 120/240V hook-up <internal configuration>).
The
PD620
can provide up to 120 amps total, 40 amps per leg (three legs)
(3Ø WYE 120/208V hook-up),
OR
*60 amps per leg (two legs) (1Ø 120/240V
hook-up <internal configuration>).
* When using Single Phase, incoming supply lines MUST be sized to accomodate
20 amps more per leg than highest per leg rating (PD66-70 amps, PD620-60
amps).
NOTE:
Delta systems have one (1) leg at a higher potential (208 Volts) in reference
to neutral, sometimes termed “Crazy Leg”, or “High Leg” typically the orange color
is reserved for designation of this line.
Do not
conect this leg into the
PD66 or PD 620.
