a Cabinet or Cutout Box Placement in or Against A Wall, Partition, or Other Support; and Accessible only from the Front "[NEC 100].

　　An Electrical Panelboard has Three Important Components Which Ensure SUPPLY of Electricity to Consumer END Powering Various Appliances.

　　Main breaker:

　　Fire. That Is why, Main Breakers Play a Significant Role in Protection of Distribution Panels.

　　Circuit breaker:

　　

　　BUS Bars:

　　Bus Are Metallic Bars (usually made of Copper or Aluminum), Use to transferred from the infan support to various feeder branches.

　　Different Feed Options Are Available in Panelboards. Feed Options Are Top Feed, SIDE Feed and Bottom Feed. Panelboards Are Mainly Categorization as Power Panelboards and Lighting PanelBoelds.

　　Lighting Panelboards:

　　We have differented Panel Lighting Panelboards, which are also known as appliance Branch Circuit Panelboards, are defined in the NEC (Article 384) as:

　　"One having more than 10% of its overcurrent devices rated 30 amperes or less for white neutral connections are privied."

　　Power Panelboards/ Distribution Panelboards:

　　Electrical Panelboards that do not fulfill the above definition will be classified under power,

　　Further Types of Distribution Panelboards Based on the Application and Requirements are:

　　Main circuit breaker Panel:

　　Main Circuit Breaker Panels Are used to propyris from overheating and keep an eye on the panel & rsquo; s ampere absility.

　　In the case of the main breaker Panel, it can cut the power of the house invite the circuit breakers.

　　Main lug panel:

　　The main lug panel can be used as a sub-panel when the main Panel relateds to it through the breaker. In case of religenecy, the power is cut before the house by disconnecting the meeting.

　　Sub-Panel:

　　Subpanels are easy and effect for homes. They are helpful in distributing the power to a spiecific part of your home from the main city breaker panel.

　　Fuse Box:

　　They are used all the electricity is controlled and distributed having three components who the main switch, Circuit Breaker and Residual Current Device.

　　Transfer Switch (ATS Panel):

　　

　　

　　Automatic Transfer Switch (ATS): When the Utility Source Office, The Generator AutomaticLlying Electrical Power.

　　Motor Control Center (MCCS):

　　Based on module digision eTC.

　　Switchboard is an Electrical Unit that regulaters the electricity from power line to various Smaller consumers.

　　as from the front and are not intended to be installed in cabinets "[NEC 100].

　　An Electrical Switchboard Has Following Main Components:

　　Panels or frames:

　　It is to hold units like switches, indicators and Other Power Deliveering and Controlling Devices.

　　Monitoring and Control Devices:

　　

　　BUS Bars:

　　It has the function to receive power and transfer it to multiple circuits mounted through the switchboard.

　　General Purpose Switchboards:

　　

　　Fusible Switchboards:

　　

　　Draw-out molded casese switchboards:

　　to lower system interruption when substituting a breaker.

　　Commercial Metering Switchboards:

　　

　　In the case of switchgear, all devices are drafn-out indicting and indictment.

　　To the interior of the enclosure is provided by Doors, Removable COVERS, or Both. "

　　An Electrical SwitchGear Has Following Main Components:

　　POWER CONDUCTING Components:

　　

　　Control System Components:

　　

　　Metal-CLAD SWITCHGEAR:

　　Then, then

　　Metal-EnClosed Switchgear:

　　

　　Pad-mounted Switchgear:

　　Protection Purposes. Switches, Fuses ETC. Are used to Safeguard Loads, RESTRICT FAULTS, and Lessen International.

　　Vault or Subsurface Switchgear:
