         1. Question #1: With respect to residential alarm systems with fire alarm devices. Is it now correct 
            to allow the system’s UL Class Two (plug in) power limited transformers to be placed into any 
            branch 110 vt non switched outlet as long as the systems monitor the AC power with an indicator, 
            and have back up power.
      2. 527 CMR 12.00,230.85(B)(3) submitted by Tony Alfano received July 10, 2025:
         1. Question #1: In the 2023 NEC as long as a breaker enclosure is marked as "suitable for use as 
            service equipment" and NOT marked as "suitable only for use as service equipment" we are allowed to 
            use this as an emergency disconnect. Are we allowed to run a 3 wire from this outdoor breaker 
            enclosure to the indoor MSP with a main breaker that is the service disconnect where the grounds 
            and neutrals will be bonded?
         2. Question #2: Per the 2023 NEC, a breaker enclosure will be used as an emergency disconnect, not service equipment. It is marked as "suitable for use as service equipment." This will be installed on the supply side of the service disconnect. Can a 3 wire be run to the MSP?

         1. Question #1: When adding a PV system to a single/two family home, by means of a supply side tap, is the 1st PV disconnect in line considered a service disconnect under article 230.70?

         1. Question #1 Does 110.26 section allow water pipe to run vertically 0.5 inches away from the side edge of the electrical panel and 6 inches out from the panel cover? When working on this panel, an electrician will have clear access to the front of the panel but may touch a water pipe with his forearm.
         2. Question #2 110.26(A)(2) Can 14-inch-wide equipment be located at the very edge of the 30-inch min. width requirement, leaving 16 inches on the other side?
