ELECTRICAL <br />1. Underwater electrical equipment can cause fatal electrical shock if not <br />installed properly. This installation has been designed in strict <br />compliance with the National Electrical Code, Article 680. Installer shall <br />install electrical equipment in accordance with NEC Article 680 and local <br />electrical codes. <br />2. A Class 'A' ground fault circuit interrupter (GFCI) shall be installed on circuits <br />supplying water feature equipment located within basins which have an <br />operating voltage greater than 15 volts. Equipment operating at less than 15 <br />volts shall be protected by a transformer which is UL Listed and marked for <br />the application. <br />3. Underwater light fixtures shall be installed so that they are submerged when <br />in operation, shall be protected by a lens guard if pointed upward, and shall <br />be protected by an integral thermal cutoff device to prevent overheating. <br />4. Underwater light fixtures shall be installed with sufficient cord length to allow <br />removal from the water for relamping and normal maintenance without <br />lowering the basin water level. <br />5. Underwater junction boxes shall be equipped with threaded conduit entries <br />and strain relief seals for cord entry. Strain relief seals serving niche mounted <br />fixtures shall make provision for both the fixture cord and an AWG # 8 copper <br />bonding wire when required by local code. <br />6. Underwater junction boxes, or junction boxes mounted outside the basin but <br />below the water level, shall be potted using 3M "Gella" 4441 or "Scotchcast" <br />2114 re -enterable potting compounds. Conduit entries shall be sealed prior <br />to potting the junction box to prevent potting compound from entering the <br />conduit system. <br />7. Stub -ups for conduit mounted underwater junction boxes must be of red brass <br />pipe. Non-metallic conduit may not be used for support of junction boxes. <br />8. Wire pulled between water feature electrical controls panels and underwater <br />junction boxes shall be of stranded copper, water-resistant type selected and <br />sized for the application. <br />9. Conduit shall be sealed to prevent entry of moisture and to prevent water <br />from draining into the water feature electrical control panels. <br />10/31/2006 <br />P8101 Design Package(7-7-06).doc <br />
