National Electric Code – Key Requirements & Example

•! Per NEC Section 725 regarding Class 2 wire •! Max Power per circuit at Power Source: 100VA •! Max Voltage at Power Source: 60V (-48V typical)

EXAMPLE

High Power Line leaves 48V DC Supply – Example 50Amp

Fuse Panel brings power below 100W: Example 48V x 1.5Amp fuse = 72W

3 16AWG Cu Pair leave Fuse Panel @ max 72W / each. Will use a pair for each modules within QSX cabinet

Cu Pairs travel 500ft Power Draw of 58.1W for 700 and AWS add-on’s and 39.2W for Cell/PCS RHU

** New ATT requirement requires that we design to -41.89VDC to maximize battery life (41.89 x 2Amp = 83.78 max output)

Fiber Distribution Strategies

•! Remote unit locations in closets or IDFs

•! Pull fiber to each remote unit location –! Single mode up to 2

km, Multi-mode to 300 meters.

–! 2 strands per remote min, typically 6-24

•! Patch panels at the Head end and Remote

•! Larger installations may have splice point at fiber aggregation points
