Yes, Years ago. I didn't think T splices were still available. I would not put one in nor would I approve one on our system. Put in two straight splices and two elbows in the pot. The PoCo will thank you later, plus the terminations may be easier to find.have any of you guys ever done a T splice on primary side of an electrical service. power company have approved t splicing primary to set a trans. for a house half way down a long driveway.
