TAPS

The city of Frisco does not accept the B-TAPs for line side connections, they only accept IT-350 Polaris Blocks for line side terminations.

When calling out a line side tap one of the two following builds should be designed, based on the as-built conditions.

Meter can ONLY outside (readily accessible):

  • (N) non fusible disconnect outside next to meter to serve as the emergency disconnect (NEC 2020: 230.85) .
  • Show two port lugs on the line in side of the disconnect with the inverter/combined inverters output terminated on the second port (first port tied to the utility supply).
  • Include all subsequent parts in BOM

Meter can AND disconnect located outside (readily accessible):

  • Perform a Hoffman/tap box tap at the existing disconnect.
  • Indicate on single line that the tap connecters used are Polaris IT-350 and clearly show tap in the junction box NOT the disconnect.
  • Include the confirmation letter in the files section
  • Include all subsequent parts in the BOM
