Abstract
Power distribution busses and methods are disclosed that provide flexible protection and alarming capabilities. Various embodiments provide interchangeability of fuses and circuit breakers within the same power distribution bus configuration. These various embodiments also provide discrete alarming for fused lines, discrete alarming for lines with circuit breakers, combined alarming for lines having mixed forms of protection, and/or selectable alarming such as combined versus discrete in relation to employing all fused lines, employing all circuit breaker protected lines, or employing mixed line protection.
Claims31
A power distribution bus alarm circuit comprising:
- a first and a second socket, each having three alarm connections and two power connections plugged into the bus;
- an alarm circuit connected to first and second alarm connections of the first and second sockets, the alarm circuit being responsive to a voltage being applied from the first of the three connections of the first or second socket and being responsive to a voltage being applied across second and third connections of the first or second sockets;
- a second alarm circuit connected to first and second alarm connections of the first socket, the alarm circuit being responsive to a voltage being applied from the first of the three connections of the first socket and being responsive to a voltage being applied across second and third connections of the first socket;
- and
- a third alarm circuit connected to first and second alarm connections of the second socket, the alarm circuit being responsive to a voltage being applied from the first of the three connections of the second socket and being responsive to a voltage being applied across second and third connections of the second socket.

A method of employing fuses and circuit breakers with a power distribution bus, the method comprising:
- inserting a fuse with an alarm connector in a first socket, the first socket connected to and receiving power from a power distribution bus;
- inserting a circuit breaker with a pair of alarm connectors in a second socket, the second socket connected to and receiving power from the power distribution bus;
- inhibiting a response from a common alarm circuit until either the fuse is blown or the circuit breaker is tripped;
- inhibiting a response from a second alarm circuit electrically linked to the first socket until the fuse is blown;
- inhibiting a response from a third alarm circuit electrically linked to the second socket until the circuit breaker is tripped.

- a power distribution bus;
- a first socket electrically connected between the power distribution bus and a power distribution circuit, the first socket including at least one alarm connection and configured to receive a fuse or a circuit breaker;
- a second socket electrically connected between the power distribution bus and a second power distribution circuit, the second socket including at least one alarm connection and configured to receive a fuse or a circuit breaker;
- a first alarm circuit electrically connected to the at least one alarm connection of both the first and second sockets, the first alarm circuit being responsive to a voltage being applied from the at least one alarm connection of either of the first and second circuits;
- a second alarm circuit electrically connected to the at least one alarm connection of the first socket, the second alarm circuit being responsive to a voltage being applied from the at least one alarm connection of the first circuit;
- and
- a third alarm circuit electrically connected to the at least one alarm connection of the second socket, the third alarm circuit being responsive to a voltage being applied from the at least one alarm connection of the second circuit.
