Abstract
An AC power line protection device which includes miswiring protection has an indicator lamp which lights when the device is in the tripped condition and turns off when the device is reset. The protection device also includes a protective circuit which protects the AC power line from downstream faults. The indicator lamp and/or the protective circuit are powered via the hot line bus bar by connecting a breaker spring to the hot line bus bar. A contact post is then connected between the breaker spring and an underside of a printed circuit board where power is provided to the indicator lamp and/or the protective circuit.
Claims16
A protection device connected between hot and neutral conductors of an AC power line, comprising:
- at least one breaker spring for operatively associating a breaker coil with a set of interrupting contacts;
- wherein said interrupting contacts include a hot bus bar;
- said at least one breaker spring is electrically connected on a first end to said hot bus bar;
- a contact post;
- said at least one breaker spring is electrically connected at a second end to a first end of said contact post;
- and
- an indicator lamp electrically connected between said hot conductor on a line side of said interrupting contacts and a second end of said contact post.
A protection device connected between hot and neutral conductors of an AC power line, comprising:
- at least one breaker spring for operatively associating a breaker coil with a set of interrupting contacts;
- wherein said interrupting contacts include a hot bus bar;
- said at least one breaker spring is electrically connected on a first end to said hot bus bar;
- a contact post;
- said at least one breaker spring is electrically connected at a second end to a first end of said contact post;
- and
- a protective circuit electrically connected between said hot conductor on a line side of said interrupting contacts and a second end of said contact post.
A protection device connected between hot and neutral conductors of an AC power line, comprising:
- interrupting means for interrupting at least one of said hot and neutral conductors between a line side of said protection device and a load side of said protection device;
- said interrupting means include a hot bus bar;
- indication means for indicating an activation of said interrupting means when said protection device is properly wired on said line side and said load side;
- and
- means for powering said indication means from said hot bus bar.
A protection device connected between hot and neutral conductors of an AC power line, comprising:
- a protective circuit including a breaker coil operatively associated with a set of contacts;
- at least one resistive element connected at one end to said hot conductor, wherein connecting AC power to load terminals of said protection device opens said contacts, and wherein connecting AC power to line terminals of said protection device permanently clears said at least one resistive element;
- a normally closed switch in series with said at least one resistive element, such that when said switch is open, testing of said protection device is enabled without permanently clearing said at least one resistive element;
- and
- said switch includes a torsion spring.
