bends at the outlets. The Conduit must be permanently and effect-
ivel~ grounded, by means of approved grounding clamps or othe~ approv-
ed devices, to a suitable ground connection, as provided in Section
(d) Wires must not be drawn in until all mechanical work on the
building has been, as far ae possible, completed. Conductors in.
vertical conduit risers must be supported within the conduit system
in accordance with the following table:
No. 14 to 0 every 100 feet.
. No. 00 to 0000 every ~0 feet.
No. 0000 to ~0,000 0.M. every ~0. feet.
No. 3~0,000 C.M. to 500,000 C.M. every ~0 feet'.
~00,000 C.M. to 7~0,000 C.M. every ~0 feet.
About 7[0,000 C.M. eve'ry 3~ feet.
A tu~ of ninety' (907 degrees in the conduit systemwill con-
stitute a satisfactory support as per above table. The following meth-
ods of supporting cables are recommended: (1) Junction boxes m~v be
inserted in the conduit e~stem 'at the required interVals in which
insulating supports of approved type must be installed and secured
in a satisfactory manne~ sc as to withstand the weight of the conduct-
ors attached thereto, the boxem to be provided with Proper covers.
(2) Cables ma~ be supported in approved Junction boxes on two
or more insulating supports so placed that the conductors will be
deflected at an angle of not less than ninety (~0) degrees, and car-
ried a distance of not less than twice the diameter of the cable from
its verticle position. Cables so suspended may be additionally
cured to these insulators by tie-wires. Other methods, if used, must
must be approved b]~ the ~lectrical Xnspectore.
(e) Must have the two or more wires of ~. circuit drawn in the
same conduit.
(f) The same conduit m~t never contain circuits of different
s~stems, but may contain two or more circuits of the same system. The
vires must lsave the conduit ~through approved bushings.
See.'. 41. (a) l[irel must have ~n approved rubber insulating cover-
lng an~ be rigidlz supporte~' on non-combustible, non-absorptive, in-
sulators which separate the wiree at least one' (1) inch.: from tlxe sur-
face Wired over'. ~houl~ preferabl~ be run singly.' on .separate timbers,
or sudtings, aud must be.kept at least five (5). inches apart. Special
attention must be given that the wires be tire,tight, but no strain
must be placed on the Joints in wires, or around the ends of tubes or
on outlet tubing, and a sufficient number of knobs mu~t be used at
these points to prevent such strains.
· (b) Must be s,parate~ from contact with the walls, floor timbers
and partitions through which they me~ pass by non-combustible, non-
absorptive insulating tubes, such as glass or porcelain. (See also
Section 11. )
(o) Rigid supporting requires, un,er ordinary conditions, where
wiring along flat surface, supports at least every fou~ and one-
half (4~) feet. If the Wires are liable to be disturbed, the distance
between sulrports should be shortened. At distributing center, out-
lets or switches where apace is limited and the five (8) inch sep-
arati0n, c~nn_Ot be maintained, each wire m~st be separately encased
