Molded Case Circuit Breakers

Molded Case Circuit Breakers are used to efficiently distribute power throughout an electrical system. They provide a means to manually open or close a circuit, and are designed to protect wiring and equipment by automatically opening under an overload or short circuit condition. In the United States, most Molded Case Circuit Breakers (MCCBs) are listed …

Types of Low Voltage Busway

The two types of low voltage (LV) busway are feeder and plug-in. They are commonly intermixed on runs of busway and plug into each other. Feeder Busway Sometimes called low impedance busway Used to feed power to a distant point Beneficial because the voltage drop over the run is generally low (somewhat lower than plug-in …

What is Busway?

Busway is an economical, modern method of distributing electricity within a building. It is similar to the tracks that an electric model train runs upon, both in look and in function. Train track sections can be snapped together to form a number of different paths for the train to follow. Likewise, sections of busway can …

ventilation

Ventilation introduces outdoor air to replenish the oxygen supply and rid building spaces of odors and toxic gases. Ventilation can also be used to pressurize a building to reduce infiltration. While ventilation is required in nearly all buildings, the design of a ventilation system must consider the cost of heating and cooling the ventilation air. …

humidification

Low humidity can cause problems such as respiratory discomfort and static electricity. Humidifiers can humidify a space either directly or through an air handling system. For satisfactory environmental conditions, the relative humidity of the air should be 30 to 60 percent. In critical areas where explosive gases are present, 50 percent minimum is recommended. Humidification …

types of security countermeasures

There are three types of Security Countermeasures: Hi-Tech, Lo-Tech, and No-Tech. These three must be used in combination to create a layered and effective security program. No single security countermeasure is effective against all threat scenarios. Access Control Systems, in particular, are a type of “controlled vulnerability” as each access control portal is a hole …
