Distribution Lines

The construction of distribution lines requires consideration of induced noise control
and voltage drops.
6.6.1 Induced noise control
(1) Distribution line to the distribution panel
A cable enclosed in a metal conduit or a copper- or iron-shielded cable must be used
for the distribution line between power supply facilities and the distribution panel in
order to protect the cable against noise induced from other distribution lines.
Alternatively, use a dedicated shaft to isolate the distribution line from other lines.
(2) Distribution line to power supply facilities
A cable enclosed in a metal conduit or a copper- or iron-shielded cable should be used
for the distribution line between a transformer and power supply facilities, such as an
uninterruptible power supply (UPS), to allow for switching to direct distribution in
times of power supply facility failures or during inspection.
