Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
140 words
In an integrated building electrical load management system, the combination of, a power line panelboard having a plurality of circuit breakers for controlling electrical loads; printed circuit board means having a plurality of conductor connections and of breaker connections; electronic control means for providing electronic control and diagnostics for the circuit board means and having a plurality of conductors leading to the conductor connections; and each circuit breaker including a remotely controlled solenoid for mechanically actuating the circuit breaker for opening and closing a circuit through a load and which solenoid includes control wires connected to selected breaker connections, said circuit breaker as thusly configured operating as a controlled switch in addition to providing a circuit protective function; whereby the printed circuit board means functions as a circuit breaker interface between the separate circuit breakers and the electronic control means.
Claim 2
Dependent Claim
140 words
In an integrated building electrical load management system, the combination of, a power line panelboard having a plurality of circuit breakers for controlling electrical loads; printed circuit board means having a plurality of conductor connections and of breaker connections; electronic control means for providing electronic control and diagnostics for the circuit board means and having a plurality of conductors leading to the conductor connections; and each circuit breaker including a remotely controlled solenoid for mechanically actuating the circuit breaker for opening and closing a circuit through a load and which solenoid includes control wires connected to selected breaker connections, said circuit breaker as thusly configured operating as a controlled switch in addition to providing a circuit protective function; whereby the printed circuit board means functions as a circuit breaker interface between the separate circuit breakers and the electronic control means.
Claim 3
Dependent Claim
32 words
The combination of claim 1 in which the panelboard and printed circuit board means are contained within an enclosure and the circuit breakers being individually connected to the printed circuit board means.
Claim 4
Dependent Claim
13 words
The combination of claim 2 in which each circuit breaker controls one load.
Claim 5
Dependent Claim
17 words
The combination of claim 3 in which the conductor connections are electrically interconnected to corresponding breaker connections.
Claim 6
Dependent Claim
20 words
The combination of claim 4 in which the plurality of conductors of the electronic control means extend through the enclosure.
Claim 7
Dependent Claim
33 words
