INPUT WIRE SIZE, GROUNDING AND OUTPUT WIRING

Refer to the latest edition of The National Electric Code Requirements for
A. Conduit should be used for both input and output wiring.
B. Input wire size is based on the NEC table 310.16. Specifying not more than 3 connections in a raceway
based on an ambient of 30°C and wire rated for 90°C (Note: amperages will need to be adjusted for
40° C ambient applications).
C. Input phase conductors are terminated directly to the input circuit breaker terminals.
Wire range:
380 VAC
400 VAC
415 VAC
D. Input ground lug TA-250, max wire range 6 AWG - 250 MCM.
E. Output is a 4 wire (5 including ground). If four (4) current carrying conductors are used in a raceway
the neutral is assumed to be current carrying and the wire must be de-rated as indicated in table 310.6
on the NEC.
Example: 1.
2.
3.
NOTE: Installation is subject to local codes - verify with a local electrical inspector.
F. All output ground and neutral terminals are PK9 grounding bar with a TA 2/0 lug.
PK9 wire range #14 AWG to #4 AWG. TA 2/0 lug wire range #14 AWG to 2/0AWG.
Output connections are made directly to the output breaker(s) and the output neutral and ground bus
provided. The load current is not to exceed 80% of the output breaker(s) rating, and not to exceed
the rated total current.
Output wiring sizes:
400/230 VAC
400/230 VAC
G. Output neutral to ground bonded during manufacturing of the power conditioner. Output Neutral is
already grounded by the factory.
H. Installation is subject to local codes. Verify with a local electrician inspector.

Assume #10 wire max current = 25 Amps.
Multiply 25 x .8 = 20
20 Amps is max current for #10 wire in a raceway with 4 conductors.
