What is the main function of the switchboard?
Switchboards consist of various electronic apparatus used to operate electric circuits. The function of a switchboard is to transmit electricity from one source to another.
What is a switchboard panel?
Switchboards are defined in the NEC as “A large single panel, frame, or assembly of panels on which are mounted on the face, back, or both, switches, overcurrent, and other protective devices, buses, and usually instruments. Both bolt-on breakers and drawout breakers can be installed inside a switchboard lineup.
What is a electrical board?
A distribution board (also known as panelboard, breaker panel, electric panel, DB board or DB box) 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.
What is the difference between a switchboard and a panel board?
Panelboards are typically flush mounted or surface mounted and are limited to a maximum of 1,200 A incoming current (main). Switchboards are free-standing units that are front connected and, like panelboards, require only front access. However, switchboards can allow for both front and rear access if desired.
What are circuit board wires made of?
The substrate most commonly used in printed circuit boards is a glass fiber reinforced (fiberglass) epoxy resin with a copper foil bonded on to one or both sides. PCBs made from paper reinforced phenolic resin with a bonded copper foil are less expensive and are often used in household electrical devices.
What is switch board wiring?
A switchboard is a component of an electrical distribution system which divides an electrical power feed into branch circuits while providing a protective circuit breaker or fuse for each circuit in a common enclosure.
What is the difference between distribution board and switchboard?
What is the difference between a main switchboard and distribution boards? This switchboard will provide power feeds to other distribution and sub-distribution boards within your building. A distribution board may be positioned on a floor with a sub-distribution board providing a feed into a server room.
