(1) Indoor. Indoor installations shall comply with
110.26(F)(1)(a) through (F)(1)(d).
(a) Dedicated Electrical Space. The space equal to the
width and depth of the equipment and extending from the
floor to a height of 1.8 m (6 ft) above the equipment or to
the structural ceiling, whichever is lower, shall be dedicated
to the electrical installation. No piping, ducts, leak protection
apparatus, or other equipment foreign.
(b) Foreign Systems. The area above the dedicated
space required by 110.26(F)(1)(a) shall be permitted to contain
foreign systems, provided protection is installed to
avoid damage to the electrical equipment from condensation,
leaks, or breaks in such foreign systems.
(c) Sprinkler Protection. Sprinkler protection shall be
permitted for the dedicated space where the piping complies
with this section.
The sprinkler piping is permitted in dedicated space but need to comlies with this section, this is very conflict, sounds like if we install sprinkler piping in dedicated space we have to protect it. This sounds conflict with freign system piping. (-:
