Section 6: SPDU Guide Specifications

60 SPDU Technical Handbook

2.6 COMPUTER-GRADE GROUND

A. The SPDU must include a computer-grade, single-point ground that complies with electronic

equipment manufacturer’s requirements IEEE 1100-1998.

B. A further requirement is that the neutral point be solidly bonded.

2.7 OUTPUT DISTRIBUTION PANEL BOARDS

A. The SPDU enclosure must be capable of accommodating two 42-pole, 225 amp, 240V, three-

phase distribution panel boards. The unit must also be capable of accommodating up to seven

225 amp frame (AF), 3-pole, molded case circuit breakers (MCCBs) in place of one of the 42-

pole panel boards, and up to eleven 225 AF MCCBs in place of both 42-pole panel boards.

B. Each distribution panel board must be individually protected by a main input circuit breaker

having a short-circuit rating of 65,000 RMS symmetrical amperes at 240 VAC.

C. Each distribution panel board must be constructed with copper busbar, and be capable of

accepting 1-pole, 2-pole, and 3-pole circuit breakers that are rated up to 100 amps.

D. Each distribution panel board must include isolated neutral and safety ground bars for

terminating branch circuit wiring. These bars should ideally be located on either side of the

distribution panel boards to facilitate installation.

2.8 BRANCH CIRCUIT BREAKERS

A. Each branch circuit breaker must provide over-current protection.

B. Each branch circuit breaker must be equipped with three (3) toggle positions: ON, OFF, and

TRIPPED.

C. All branch circuit breakers must be 1-pole, 2-pole, and 3-pole types and rated 15 amps through

100 amps.

D. All branch circuit breakers must have a minimum rating of 10,000 RMS symmetrical amperes

at 120/240 VAC.

2.9 OUTPUT POWER CABLES

A. The SPDU enclosure must accommodate up to 84 output power cables per 84 pole positions.

B. All output power cables must be able to exit the SPDU at either the top or the bottom of the

enclosure.
