SCCR Panel Ratings
 Having the wrong short
circuit current rating (SCCR) on control panels,
machinery, and even HVAC systems can be a major
source of liability for companies if equipment or
an employee is hurt by an arc flash.
Unfortunately, having the right SCCR is a
responsibility shared by everyone from the panel
design engineer to facility personnel. Learn how
NEC 110.10 requires SCCR to be equal or greater
than maximum short circuit currents, regardless of
whether the panel is new, or has been updated.
Either way, you need to know your risk,
responsibilities, and liability if you want to
avoid the SCCR trap...Read More
When Do You Need 100%
Rated Breakers?
If the continuous load
is more than 80% of a standard circuit breaker
rating, you better tell the customer they need a
100%-rated breaker. Balancing the load with
another panel under 80% is one way to avoid this
problem. Otherwise, double check that the
enclosure is rated to handle 100%-rated breakers
and that the all parts are correctly labeled...Read More

Tech
Talk: Answer the Challenge for Chance to
Win a 4GB IPOD!!  CONGRATULATIONS to
Joe Korus of Coffman Engineers, Inc. out of
Spokane, Washington for winning last month's Tech
Talk Challenge by answering the eternal question:
"What, exactly, does a fuse protect?" This will take you to the
answer for last month. In April, we're going with
another electricity-related movie
question. While you are reading the question
and emailing us your answer, be sure to poke
around the PEARL site and find out the latest on
electrical reconditioning. We draw one winner from
all correct entries received by the end of
month. 2,300 electrical related keyword

How
To: Inspect, Recondition and Test Low Voltage
Plug-In Type Bus Duct and Feeder Type Bus
Duct
As
building and plant sizes grow, it can be cost
effective to distribute plant power using plug-in
bus systems as the primary conductors rather than
conduit and wire. These devices usually include
circuit protection by way of fusing or circuit
breakers. Feeder bus systems are typically high
current systems where running wire would demand
that the conduits be very large and run in
multiples in order to provide the necessary
current. Feeder duct allows very high current runs
in single enclose busways but these are not
designed to provide disconnecting means along the
way...Read More
