circuit will be allowed if the sockets have a spacing of not mole than four (4) <br />inches to center to center. <br />Branch circuit wires for each section for attraction board signs shall be <br />carried to the distributing center of the section in rigid conduit. <br />Provision shall be made for the ventilation of attraction board signs <br />illuminated by lamps on the inside. <br />Circuits for canopy ceilings shall be limited to sixteen (16) sockets. <br />(C) LOAD. Mains feeding signs shall be calculated on the basis of full con- <br />nected load, whether flashers are used or not, but in no case shall there be a <br />capacity for less than ten (10) watt lamps. Where more than one reading matter <br />is overlaid on a single panel and only one reading matter is illuminated at one <br />time, the mains may be calculated on the basis of the maximum load at one time. <br />(D) WIRING OF SOCKETS. Wires shall be soldered to terminals of sockets and <br />exposed parts of wires and terminals shall be treated to prevent corrosion. <br />(E) BUSHINGS. Approved bushings shall be employed to protect wires passing <br />through walls or partitions of the sign structure. <br />(F) SWITCHES. Each sign shall be controlled by a switch which will open all <br />ungrounded conductors. <br />If transformers are installed inside the building wall and switch shall <br />be installed at the transformer location. Switch may be installed inside flat <br />or recessed signs or letters if special permission is obtained. In these cases <br />covers over handholes must be clearly marked with a metal tag to indicate loca- <br />tion of switch. <br />All switches shall be 0 to 30 ampere knife blade contact and if mounted <br />outside of sign shall be in weatherproof enclosure. An electrically operated <br />magnetically held contactor shall be employed as control switch on all neon <br />signs requiring more than six (6) circuits. <br />The coil circuit shall be controlled by single pole switches in series, <br />one of which shall be located at magnetically held contactor. <br />12 <br />
