AT&T AT&T manual AC Power Requirements, Single Cabinet System

AC Power Requirements

●The System 25 power service shall be a dedicated branch circuit with no other equipment served (See Figure 6-3. )

●Each cabinet requires 500 Watts at 115V ac (maximum)

● Provide a load center of appropriate current rating (ITE EQ4 typical) equipped with 120V ac, 15 ampere (AMP), single pole magnetic circuit breaker(s) (ITE QP1-B015 typical ). Each breaker is to protect 2 associated wall mounted 115 V ac, 15 AMP, receptacles (HUBBELL 5262 typical). Grounding of this load center is to be provided by a “Green Wire” ground extended from the grounding electrode conductor at the AC service entrance to the load center.

The following materials are required:

A.Single Cabinet System

1 - 15 AMP 3 Wire Dedicated Branch Service

1 - 4“ Box (RACO 230 or Equiv.)

1 - 4“ Cover (RACO 807 or Equiv.)

1 - Ground Bar (Square D PK9GTA or Equiv.)

2 - Recpt. (Hubbell 5262 15 AMP or Equiv.)

B.Multiple Cabinet System

2 - 15 AMP 3 Wire Dedicated Branch Service

2 - 4“ Box (RACO 230 or Equiv.)

2 - 4“ Cover (RACO 807 or Equiv.)

1 - Ground Bar (Square D PK9GTA or Equiv.)

4 - Recpt. (Hubbell 526215 AMP or Equiv.)

C.Typically, multiple cabinet systems can be powered from a single phase 120V ac, 60 Hertz service (two 15 amp circuits required. ) There are no phase restrictions between cabinets. Therefore the two 15 amp circuits required may be derived from single or three-phase service.

D.The receptacles shall be located at least 1 foot above the floor. Receptacles shall not be located further than 4 feet from the cabinets.

DANGER

Under no circumstances should this equipment

be connected to 220V ac; doing so poses a

serious fire hazard.
