Hi Wrenches - Occasionally we will do supply side connection for our PV systems. As of 1/1/2023 in CA, we follow the 2020 NEC 705.11 Supply-Side Source Connections section. Recently, an inspector asked us to comply with the following:
230.46 Spliced and Tapped Conductors Service-entrance conductors shall be permitted to be spliced or tapped in accordance with 110.14, 300.5(E), 300.13, and 300.15. Power distribution blocks, pressure connectors, and devices for splices and taps shall be listed. Power distribution blocks installed on service conductors shall be marked "suitable for use on the line side of the service equipment" or equivalent. Effective January 1, 2023, pressure connectors and devices for splices and taps installed on service conductors shall be marked "suitable for use on the line side of the service equipment" or equivalent. When we reached out to one supplier of insulation piercing connectors (ILSCO), they responded: "We are still in testing, I just checked and from what I see there are no products listed for this new requirement yet by any manufacturer." Has anyone bumped into this before and/or have any proposed solutions? Best, August Luminalt
