We do enough pole mounts that we started making our own racks. Similar to DP&W, but we weld the head directly to the pole, and incorporate a screw jack that makes tilt adjustments easier.<div>Our inspector hasn't given us any trouble about the exposed wiring, but we keep it pretty clean and secure, and mount the combiner box just below the head, to limit the unprotected wiring. </div><div>We're protected to below 6 ft, but not 8 ft. Where does it say 8 ft? </div><div>398.15 C covers 'open wiring methods' and says conductors above 7 ft are considered protected from physical damage. Bill Brooks said 8 ft in his excellent presentation, but I never found the code reference to that exact height.</div><div>110.27 A 4 : 'Guarding of Live Parts' says 8 ft height, but this is for protection from exposed bare conductors or exposed live parts. All of our gear is insulated, no exposed live parts, so I think 398.15C is closer to being applicable. 690.31A says all wiring methods included in the code shall be permitted, so again 398.15C with 7 ft height seems to work.</div><div><br></div><div><br></div><div>Thanks,</div><div><br><div>
