Cal. Code Regs. Tit. 8, § 2847 - Distribution Cutouts and Fuse Links-Expulsion Type
(a) Installation. The cutouts shall be so
located that they may be readily and safely operated and refused, and so that
the exhaust of the fuses will not endanger persons. Distribution cutouts shall
not be used indoors, underground, or in metal enclosures.
(b) Interrupting Rating. The interrupting
rating of distribution cutouts shall equal or exceed the maximum fault current
which can occur at the fuse location. The available fault current at the fuse
location shall include contributions from all connected sources of energy, such
as the other lines, generators, large motors, etc.
(c) Voltage Rating. The maximum voltage
rating of cutouts shall equal or exceed the maximum circuit voltage.
(d) Operation. Where fused cutouts are not
suitable to interrupt the circuit manually while carrying full load, an
approved means shall be installed to interrupt the entire load.
Unless the fused cutouts are interlocked with the switch to prevent opening of the cutouts under load, a conspicuous sign shall be placed at such cutouts reading, "Warning--Do Not Operate Under Load."
(e) Identification.
Distribution cutouts and fuse links shall have a permanent and legible
nameplate or identification including the following information:
(1) Cutout Body, Door, or Fuse Tube.
Manufacturer's type or designation, continuous current rating, maximum voltage
rating, interrupting rating.
(2)
Fuse Links. Continuous current rating, type identification following the
continuous current rating.
(f) Structure Mounted Outdoors. The height of
cutouts mounted outdoors on structures shall provide safe clearance between
lowest energized parts (open or closed position) and standing surfaces. For
mounting heights, see Articles 19 and 35.
(g) Clear Workspace. Space shall be provided
for fuse handling in accordance with Article 35.
