"NUISANCE TRIPPING"
A nuisance trip occurs when it mistakes a normal operating condition for a hazardous condition,
Also, it is a nuisance to constantly have to reset a defective circuit breaker. However, it may not be defective, it may be a warning that the wiring and its connections are being overloaded with too much current or too many appliances.
Never try to solve the problem of a nuisance tripping circuit breaker by putting in a higher rated breaker; i.e., a 30 amp breaker in place of a 15 or 20 amp breaker.

How Powerboss Works
![Page 20: Master distributor of intelligent motor controller starters is looking for investor](https://reader033.vdocuments.us/reader033/viewer/2022052311/559dff261a28ab66098b481a/html5/thumbnails/20.jpg)
How Powerboss Works
Torque is proportional to the applied voltage squared: T∞V²
The Powerboss adjusts the output voltage to the motor according to the torque required
This in turn decreases the current.Voltage and current are common to all three
sides of the power triangle
![Page 21: Master distributor of intelligent motor controller starters is looking for investor](https://reader033.vdocuments.us/reader033/viewer/2022052311/559dff261a28ab66098b481a/html5/thumbnails/21.jpg)
How Powerboss Works
The Power triangle is reduced from all three sides saving energy in three components:
Kva which is the total energy applied which will put less strain on the supply as less current is drawn.
Kw which is paid for.Kvar the reactive component causing heating
and vibration in the motor (all the nastiness).
![Page 22: Master distributor of intelligent motor controller starters is looking for investor](https://reader033.vdocuments.us/reader033/viewer/2022052311/559dff261a28ab66098b481a/html5/thumbnails/22.jpg)
Powerboss is not designed to increase the PF significantly
If you look at the power triangle the lagging angle is only decreased by a small amount even although there is a significant drop in Kvar. The reason for this is the triangle is affected from all three sides.

If you look at a capacitor it affects Kvar only so it changes the triangle differently see below;
Power Factor correction is designed to counter act the KvarL in the system thus only improves the PF and reduces LPF penalty

USING POWERBOSS AS A SOFT STARTER YOU CAN:
Prevent dips in supply when starting larger motors
Attach more equipment to a single supplySwitch your motors On & Off at any time due
to reduced starting currentSignificantly increase the life of contactors &
drive train componentsReduce the worry of Peak Demand penalties
during starting
