What are the recommended materials for re potting GE Magneblast breaker bottles. Ours are showing signs of cracking and seperation between the bar and potting compound. We were smelling ozone, and called in a specialist. He chiseled out the old potting compound re wrapped the bars with silicone tape, and bought some tar from Home Depot to fill the bottle up with. We had a few bus joints that showed signs of partial discharge also. The joints were enclosed within a plastic case tied together with string and filled with a tar like compound. These cases were removed, the bolts retorqued, and were covered with silicone tape. The cases were not reinstalled.
Is there a special compound that should be used, or is roofing tar sufficient? We would like to inspect the bus during our outage, but are unsure whether to use the same contractor.
