Re: CQD answer published Monday, November 25, 2019 -Warning Ribbon for Underground Service Conductors
Question regarding the Warning tape over HDPE. We are on a project now. They are doing horizontal boring to install feeders to carports that supply the AC to inverters. With horizontal boring there is no way to install warning tape. How is this addressed? It there an exception?

Answer:
Hey Vern thanks for your follow up question. There is not an exception to 300.5(D)(3) but the rule only requires a warning ribbon to be places in a trench for directly buried underground service conductors, not as in your case for feeders. Also, for directional boring there is no trench.
