I am concerned that the 16AWG conductors included in the power cable introduce a number of electric code concerns when installed inside the panel and connected directly to a circuit breaker.
First, I am aware of no circuit breaker manufacturers that sell 15A (or larger) residential breakers listed for conductors smaller than 14AWG. Terminating the 16 AWG conductors directly on these breakers as identified in the installation guide would be a violation of the breaker’s listing.
Second, article 240.4(D)(2) of the NEC requires that 16AWG conductors be protected by no-larger than 10A of overcurrent protection, except in cases of tap conductors, transformer secondary conductors, and other specific applications. I am unable to find any exceptions for other specific applications that would encompass the Sense installation, even in Article 750 which addresses Energy Management Systems and monitors.
Is it possible that I am interpreting this incorrectly, or is there a permitted exception in the NEC that I’m unaware of?
