In this short video we use BS7671 On-Site Guide to workout the minimum heights for catenary wires used to support cable above ground level between buildings. Using Appendix D table D2 in the On-Site Guide we can find the minimum distances in areas accessible and inaccessible to vehicles for these catenary wires. The video includes footage of catenary wires supporting cables to help you understand the requirements of BS7671.

Videos are training aids for City and Guilds (C and G) and EAL courses Level 1, 2, 3 plus AM2, AM2S and AM2E.
