Turn off power supply to the electrical panel. Locate the Service Disconnect or Main circuit breaker in the panel, and set to the "Off" position. This circuit breaker is likely to be the largest value and located either at the top or bottom of the panel. If no such circuit breaker is identified in the panel, it is likely in another panel in the building, or in the meter socket enclosure. Look for other panel(s) to find the circuit breaker needed.

Inspect the circuit breaker arrangement for unused locations. Pay particular attention to unused spaces at the top and bottom of the cover. Some manufacturers of electrical panels have removable knock outs or plates at these locations, but the panel itself lacks provisions to mount a circuit breaker. Simply stated: Do not rely on the cover alone to determine the ability to add circuits to the panel - check the bus bar.

Remove the electrical panel cover. Remove fasteners while a helper...

BACKGROUND OF THE INVENTION

1. Field of the Invention

This invention relates to electric power distribution systems such as those found in residential or light commercial applications in which circuit breakers can be reclosed from a remote location using power line communications.

2. Background Information

Circuit breakers are commonly used to provide both main and branch circuit protection in homes and light commercial applications. The breakers are mounted in enclosures called load centers which are normally placed in non-intrusive locations such as basements, garages, and the like, as they usually do not require maintenance or attention. A circuit breaker is an automatic device which will trip or open immediately should an overcurrent (short circuit or overload) occur in the protected circuit. Such a condition should be, and in fact must be, corrected before the circuit breaker can be reset to reestablish the circuit. These circuit breakers also respond to...

Get the benefits of short circuit management and auto reversing without adding more boosters! PM42 Quad Power Manager lets you use a single booster and divide its output into 4 power sub-districts for automatic reversing or to improve operation by preempting booster shutdown when a short circuit is detected by the PM42. If you want to improve operation but don't need the added power (or expense) of adding a booster, the PM42 is the right answer for you. Each PM42 can run 4 sub-districts off a single booster in any combination of regular sub-districts and auto reversing sub-districts.

69 Articles Found for PM42

Q: Can two sections of a single PM42 be configured to perform both the task of a circuit breaker and also automatic reverse section control for a single reverse loop? The PM42 can be configured so that one section of the PM42 is used for circuit breaker operation, feeding into another section of the same PM42 which is configured for automatic reverse...

Where I'm Coming From

To paraphrase Richard Nixon, I am not a cable guy! Well, at least I am not an expensive cable guy. I learned early on in my adventures in high-end audio that cables DO make a difference. I worked my way up from Radio Shack 18 gauge hook-up wire to Mogami Star-Quad interconnects to Canare GS-6 Guitar amplifier cable to a couple of side-steps with Belden coax cable before I found the ultimate Poor Boy's Delight in military spec cable for mere pennies per foot. I've sat there on the riverbank, like Bob Dylan, "Watching the River Flow" as cable companies sprang up, charging ever-higher prices for their various interpretations of sonic heaven.

After a few years of listening to experts talk about the sonic advantages of having a dedicated line for the system, I had a friend install a 20-amp line in my townhouse. I reasoned that moving anyplace else was probably years away, so I might as well try it out. At that point my system was still pretty...
