Introduction; Minimum Requirements; Ac Mains - Wire Gauge - Hitachi EC702MP-BB3 Operation Manual

1. Introduction

This section provides information on the minimum installation requirements for ATSC E-
Compact Series transmitters with recommendations on shelter, tower, antennas, cables,
grounding, mains, transient preventions, etc.

2. Minimum Requirements

2.1. AC Mains - Wire Gauge

The following details the consumption with the equipment running at its maximum power.
Current (A) on each wire:
M110
110VAC ±15%

Not available or uncommonly used
*EC704MP-BB3 operates on M110 electrical network using two PSUs.
The current values specified in the table are according to the load of each phase, which
will determine the size of the conductors and protection.
Said gauge is the minimum recommended for the transmitter in question, if the cable
length is longer, consider a voltage drop in the cable maximum of 5%.
The section of the neutral conductor should be the same as the phase.
The section of the ground conductor must be the same as the conductor's phase.
