Main Distribution Panel Vs Switchboard

The main role of the switchboard is to allow the incoming electric power to be divided into smaller independent circuits according to their current requirements.

Main distribution panel vs switchboard.

Switch gears are defined as any equipments that are used to protect any type of circuits from different types of fault. Switchgear incorporates only low voltage power circuit breakers lvpcb which conform with ansi c37 13 nema sg 3 and are listed per ul 1066 whereas switchboards may include any combination of protective devices including insulated case iccb molded case circuit breakers mccb listed per ul 489. Free standing may be mounted against a wall if 45 deep allowing front. Switchboards and panelboards provide a similar functionality in a power distribution system panelboards are typically flush mounted or surface mounted and are limited to a maximum of 1 200 a incoming current main.

Your article about differences between switchgear switchboard is wrong. A distribution board also known as panelboard breaker panel or electric panel is a component of an electricity supply system that divides an electrical power feed into subsidiary circuits while providing a protective fuse or circuit breaker for each circuit in a common enclosure normally a main switch and in recent boards one or more residual current devices rcd or residual current. Switchboards are free standing units that are front connected and like panelboards require only front access. For example mcb at your home or circuit breaker in substation or isolator in switch yard can be termed as switch gears.

Panel mounting and access. The main switchboard is the first electrical panel that connects the electricity and power to the site. Unfused 15 pf power factor 30 cycles. Switchboard vs distribution panel tommom electrical 29 aug 07 10 59 another way to look at it is a switchboard is floor mounted while a panelboard is wall mounted although very large ones might reach the floor.

We will discuss the 4 main purposes of the main switchboard the pieces of equipment that are used to meet these purposes. A switchboard can therefore be used to distribute power to individual loads control equipment transformers panel boards etc. 20 pf power factor 3 cycles must have instantaneous trip funtion to maintain ul 891 rating.
