Methods and systems for measuring system loads and sub-metering electric power distribution

A load sensing assembly comprising:

• a plurality of load sensors configured to be communicatively coupled to respective load carrying branch circuit conductors, said plurality of load sensors configured to generate a load signal proportional to the load carried in the respective branch circuit conductors;
• a plurality of output leads, each said output lead coupled to an output of a respective said load sensor, said output leads coupled to a termination connector comprising a first shape and a plurality of pin connections, said pin connections configured to mate in one-to-one correspondence with said output leads, said first shape configured to mate to a complementary second-shaped connector;
• and
• an L-bracket comprising a poke-yoke configuration that facilitates preventing installation of said L-bracket in other than a predetermined orientation, said L-bracket configured to support said plurality of load sensors in substantial alignment with respective load carrying branch circuit conductors.

A method of measuring sub-branch loads in an electrical distribution panel, said method comprising:

• mounting a load sensing assembly proximate a branch circuit breaker at least partially within the distribution panel, the load sensing assembly including a plurality of load sensors, each load sensor configured to generate an output signal that is proportional to an electrical load in a branch circuit, each load sensor comprising at least one output signal lead electrically coupled to a first termination connector;
• coupling the at least one output signal lead to a signal wire using the first termination connector and a complementary second termination connector electrically coupled to the signal wire;
• and
• determining, using the respective branch circuit load signals, a load profile for at least a portion of the branch circuit.
