Transformers tubes, conductors, insulators, and other items <br />of equipment shall be of approved types. <br />Except by special permission, transformers shall be of the type <br />for which the rating does not exceed thirty millamperes secondary or 450 <br />volt amperes primary. <br />Tube shall be substantially supported and installed so that it shall be <br />free from contact with inflammable materials or grounded metal objects. Approved <br />electrode receptacles or housings shall be used on all signs, or approved <br />bhshings may be used if the high voltage cable is substantialy supported on <br />approved insulators to within two inches of each electrode and connection to <br />electrode made with pigtail soldered to cable and approved connector. <br />Transformers shall be secured in place in a reliable manner, <br />but shall not be mounted on door or hung so the entire weight is suspended <br />from a single sheet metal side, face or top. <br />Branch circuits shall be so arranged that the connected load <br />shall not place more than fifteen amperes on branch fuse. <br />High tension conductors shall not be smaller than +14 B & S <br />gauge stranded type of suitable insulation for the voltage it is to carry, <br />and shall be property supported and separated at least two inches from each <br />other. <br />No electric sign of any kind, ;�hich has been connected for test <br />shall'be left connected so that the same can be lighted until inspection has <br />been.ma.de and approval given by the Building Department. <br />Provisions shall be made for supply connection other than on <br />top of the sign. If electrode receptacles are exposed to the weather or are <br />in any position that water may enter the sign body, a rubber filler shall be <br />used to exclude the water. <br />All connections between electrodes on window signs must have <br />suitable insulator of glass or other approved insulating material over the <br />connection from cable to tube. Linen, friction or rubber tape will not be <br />considered as a protection. <br />Skeleton type window signs shall be supported by chain, wire <br />or other suitable means, insulated at tube end and supporting entire weight <br />of sign in such a manner that no strain will be placed on high voltage cables <br />Except that the provisions of this section shall not apply to <br />portable window signs bearing the Underwriter's label and spproval, and which <br />are plugged to a fixed receptacle near enough to sign that no staples, nails <br />or other holders are recuired to hold the cable in place. <br />-5- <br />
