than three (3) feet apart which separate the wires at least two (2) inches <br />from each other and from conducting materials. <br />2. Conductors within a sign or other enclosure shall have rubber compound <br />or other approved insulation or approved open conductor methods. <br />3. Sharp bends in the conductors shall be avoided. <br />4. Conductors, other than installed within a sign, shall be installed in <br />conduit, or electrical metallic tubing. Approved insulating bushings <br />shall be used where the gas tube cable enters or leaves the conduit. <br />(H) TRANSFORMERS: <br />1. Transformers shall be of a type approved for the purpose. 'Where <br />exposed to the weather they shall be of the weatherproof type, or installed <br />in tube - terminal housings or approved metal boxes. <br />2. Transformers shall be mounted on brackets directly connected to frame <br />of sign. On signs under twelve (12) square feet where frame is not re- <br />quired, transformers shall be supported on brackets fastened to the sides <br />of the sign and in no case shall the transformer be resting on bottom of <br />sign box. <br />3. Transformers shall be of types whose ratings do not exceed 900 volt <br />ampere primary nor 15,000 volt secondary open circuit voltage with an <br />allowance on test of 1000 volts additional. <br />Transformers whose secondary current ratings exceed 60 milliamperes <br />shall be provided with an automatic safety disconnect device which will <br />remove the primary voltage from the transformer when current flows to <br />ground from any part of the high voltage circuit in excess of 20 milli- <br />amperes. Such device shall operate within a period of 20 cycles or 1/3 <br />of a second. <br />4. Not more than one transformer shall be dependent upon a single auto- <br />matic over - current protective device unless the combined load does not <br />exceed fifteen (15) amperes, at 125 volts or less. Where circuit feeds <br />- 14 <br />
