Probe Installation Direct Burial Cable - Probe to Console Field Wiring15Direct Burial Cable - Probe to Console Field WiringAn alternative to trenching through existing pavement is to use direct burial cable.IMPORTANT! Maximum probe-to-console cable length is 1000 feet (305m).Prior to installing direct burial cable with epoxy splices, consult with the local authority having jurisdiction. Use ofdirect burial cable is only allowed in locations where local codes permit the use of buried cable.The direct burial method requires grinding a 1/4” to 3/8” wide by 1-1/4” deep groove (adding 1/4” of depth foreach additional cable) in the pavement surface, laying Veeder-Root supplied direct burial cable down in the bottomof the groove, laying an expanded polyethylene foam backer rod over the cable(s), and then a placing a 1/4” to 1/2” bead of Veeder-Root recommended silicone sealant over the backer rod to within a minimum of 3/8” below thepavement surface [see Figure 13].If you decide to use the direct burial method, you should order the Veeder-Root Direct Burial Cable PreparationKit, P/N 848100-500.Figure 13.
