Telecom Closet Power Technical Requirements

Verify that lighting of closets is a minimum of 540 lux (50 footcandles) measured 91 cm (3 ft) above the finished floor level.
Verify that light fixtures are located a minimum of 2.6 m (8 ft 6 in) above the finished floor.
Verify that the telecommunication closets have emergency lighting.
Verify that the TC is equipped with a minimum of two dedicated 3-wire 120 VAC duplex electrical outlets which are:
– On separate circuits
– 20 ampere rated service breakers”
Verify that the TC is equipped with two (2) dedicated 20 AMP, 120 VAC duplex electrical outlets, each on separate circuits for equipment power when equipment rack(s) are installed. Outlet(s) shall be mounted on the equipment rack that it is serving or at Ceiling level mounted directly above the equipment rack being served.
Verify that the TC is equipped with separate duplex 120 VAC convenience outlets (for tools, test sets, etc.) which are:
– Located at least 45 cm (18 in) above the floor
– Placed at 1.8 meter (6 foot) intervals around perimeter walls”
Verify that the TC is provided with backup, standby, or emergency power sources that has automatic switch over capability.
Verify that all outlets are on non-switched circuit (circuits that are not controlled by a wall/light switch or other device that may inadvertently cut power to the telecommunication systems).
Verify that Power panels for dedicated electrical service shall be provided in a TC when active equipment is planned or installed.
Verify that a ground busbar is provided where there is a requirement to bond or ground more than one connection.
Ensure that the ground busbar shall be sized (minimum thickness 1/8 inch) to carry the maximum ampere capacity during a fault condition. It shall also be large enough to connect 6 AWG (solid copper conductors) using a listed double hole connector.
