Equipotential BondingInstallationEquipotential Mesh / MatsFigure 49.1. UNROLL MESH. No digging,trenching or special equipment required- the mesh is simply unrolled over theground.2. INTERCONNECT. Sections of mesh areinterconnected using CADWELD ® TypePG connections.3. FINISHED JOB. Wire mesh cut andspliced to avoid contact with guy anchor.Wire mesh ready to be covered.EASY TO INSTALL• No digging or trenching required• Unroll over the ground• Interconnect by welding to adjacent sections of mesh using theCADWELD process• Weld to the main ground grid in substations or welded to groundrods• May be covered with a layer of earth or crushed stone depending onthe applicationINTERCONNECTING• The CADWELD process provides a rapid and economical method ofinterconnecting mesh in the field• Resulting weld is permanent and corrosion resistant• Current carrying capacity equal to that of the conductorNET WEIGHT (LBS) PER 1000 SQUARE FEETTNOTES: CS = Copper-clad Wire CU = Solid Copper WireAdd 75 pounds per roll for approximate shipping weight.SUGGESTED SPECIFICATIONSPrefabricated Wire Mesh shall be manufactured using(a)* AWG bare, solid (b)* wire on a (c)* inch x (c)* inch conductorspacing with all cross connections silver brazed using a 35% silveralloy brazing material and a non-corrosive flux. It shall be (d)* feet,(d)* inches wide by (e)* feet, (e)* inches long with (f)* inchesoverhang on both sides and both ends, and shall be wound on afiber tube with the outside of the roll protected by wood stripsinterconnected with steel wire.* (a) Wire size, #6, #8, #10, or #12 AWG.(b) 30% or 40% conductivity copper-clad or pure copper.(c) 2 inches x 2 inches minimum to 48 inches x 24 inchesmaximum (in 2 inch increments).(d) 20 feet, 4 inches maximum.(e) Maximum length determined by weight, with a 500pound maximum net weight.(f) No overhang, an overhang equal to one-half conductorspacing or an overhang equal to one-half conductorspacing plus 2 inches (for interconnecting).See Figures 46, 47 and 48 on page 48.Ph: 1-800-677-9089www.erico.com49
