APPENDIX B: SURGE PROTECTIVE DEVICE COMPATABILITY
Per 2020 NEC 230.67 Surge Protection
A surge protective device (SPD) shall be installed in all new and replacement services supplying dwelling units.
Shall be Type 1 or Type 2 SPD.
Shall be attached to the service equipment or immediately adjacent. Exception: The SPD shall not be required to be in the
service equipment if located at each next level distribution equipment downstream toward the load.
Span is compatible with virtually any standard SPD connected to a 2-pole breaker or installed on a 2-space slot in equivalent SquareD
HOM, Eaton BR, or Siemens/Murray QP/MP panelboards.
When installing an SPD, mark it as an essential circuit in the Span Installer App under Advanced settings, depicted below.
If using an SPD with usable circuits, be sure to only have essential items on those circuits (e.g., internet router, alarms, fire
detection). Homeowners will not be able to turn this circuit off via the Span Home app.
