BY AUTHORITY


Power or Railway, Telephone or"
Telegraph Circuits on Public
Roadways and Highways.
In the construction of aerial circuits
for the above purposes, the following
rules and requirements must be OBJ.
served on and after this date:
POLES.
/. Application must be made on 4,
proper blanks to the Superintendent of
Public Works for permission to erect.
2. Use of poles is limited to the pur-
pose for which they are erected.
3. Poles erected within town or city
limits, other than those for electric,
railway purposes must not be less THAI ,
forty feet in length and twelve inches
in diameter at butt.
a. Space between poles must not ex.
coed 100 feet
5. Poles subjected to special strains
must be properly guyed or braced.
Guy lines are not to be secured to
trees.
6. Poles must be stamped with own.
er's name and numbered.
Z. Private signal lines must not be
placed on poles for public service with.
out permission.
8. Where curb lines are established,
poles are to be placed inside of and
tangent to the curb line.
CROSS ARMS.
/. Must be Chamfered.
2. For high potential lines should be
dipped in oil.
3. When carrying more than two
lines must be braced with galvanized
iron braces.
4. Must be secured with galvanized
iron bolts; not lag screws.
5. Where lines of dead-ended double
cross.arms must be used.
WIRES.
]. Main conductors for electric light
or power on roads and highways musr
not be less than No. 6, B. & S.
2. Service wires on roads and high,
ways must not be less than No. G, 81
& s.; in private grounds, not less THAI
No. s, b. & s., and rubber covered. y
g. Electric light and power lines
must be kept clear of foliage. Supply
companies are responsible for lines on
roads and highways, and owners on
private grounds.
H. The lower limit of wires on roads
and highways is that of the electric
railway trolley wire, twenty.one feet
above the level of the track.
8. Where wires for various purposes
are run on the same poles, or lines
cross, the following order will be kept,
beginning with the highest:
(a) Signal wires.
Oh Telephone and telegraph
(c) High potential alternating cur.
rent.
(d) Arc light.
(e) Low potential alternating cur.
rent.
Q) Direct current, constant poten.
tial.
@. Telephone and similar wires must
be protected by dead insulated guard
irons or wires from possibility of con.
tact with other conducting wires.
Must not be placed on same cross-arm
with electric light or power wires, and
when placed on the same poles with
such wires the distance between the
inside pins on each cross-arm must not
be less than twenty-siX inches.
Z. Wires crossing fiat roofs must
clear same by at least seven feet.
Wires crossing pitched roofs must
clear ridge over which they pass, or
to which they are attached by at least
one foot.
s. Service wires must be run as
nearly as possible in horizontal lines
from poles to point of attachment to
buildings.
8. All joints in all wires must be
soldered.
INSULATORS.
l. All insulators for high potential
circuits must be of glass and triple
petticoat.
2. Insulators for other electric light
and power circuits must be glass and
double petticoat.
3. Service wires for electric light or
power where secured to the outside OF
buildings, must be carried on double
petticoat, glass insulators.
The term high potential" covers
any current between $50 volts and
$500 volts.
