What is Smdb panel?
Sub Main Distribution Boards (SMDB) : Sheet steel enclosed with Powder coating In Cabinet (Wall mounting) or Feeder Pillar (Floor mounting) design. Outdoor or Indoor type with suitable protection. Ample space for ease of cable Termination. Complete with MCCB/Switch/HRC fuses etc.
What is a sub main distribution board?
These are the switchboards that although similar construction, are larger than a final distribution board circuit. The boards are installed midway through the power distribution system, at the point in a large distribution cable ends, and several smaller starting sub-circuits.
What is SMBD in electrical?
Electrical Sub-Main Distribution Boards (SMDB) are the integral part of Electrical LV Power distribution network in the end user premises of a medium and large scale projects.
What are the components of a distribution board?
A typical electrical distribution board includes the following components – bus bar, fuse links, switches, bypass equipment and residual current detector (RSD).
What is the full form of MCC panel?
MCC PANEL. MCC stands for motor control center. A motor control center (MCC) is an assembly of one or more enclosed sections having a common power bus and principally containing motor control units.
What is the full form of Smdb?
Sub Main Distribution Board. Electronics. SMDB. Self-managing Database Systems. Database Management.
Does a sub board need a main switch?
A: No. All conductors of a sub main or a final sub circuit must be connected on one switchboard. Q: If the installation is supplied with multiple supplies do I need to have main switches for each supply at the main switchboard?
What is the difference between a switchboard and a distribution board?
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.
What is DB electrical?
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 function of a distribution board?
The Distribution Board, refers to an equipment which consists of bus bars, and possible switches, fuse links and Automatic protective equipment, bypass equipment, for connecting, controlling and protecting a number of branch circuits fed from one main circuit of a wiring installation in a building or premises for easy …
How many circuits can a distribution board have?
A normal new domestic CU used as a main panel might have from 6 to 24 ways for devices (some of which might occupy two ways), and will be split into two or more sections (e.g. a non-RCD section for alarms etc., an RCD-protected section for socket outlets, and an RCD-protected section for lighting and other built-in …
What is full form of Rccb?
RCCB stands for Residual Current Circuit Breaker. Both phase and neutral wires are connected through a RCCB device. These are an extremely effective form of shock protection&widely used for protection from a leakage current of 30,100 & 300mA.
Where is the sub main distribution board ( SMDB ) installed?
Sub Main Distribution Board (SMDB) The boards are installed half way through the mains distribution system, generally at the point where a large distribution cable terminates, and several smaller sub-circuits start. The board may be fitted with HRC fuses, MCB’s or MCCB’s. It may hence take the form of a large fuse board or and LV panel board.
What are the duties of a submain distribution board?
Ensure that the wiring termination to the Sub main Distribution Board are complete, tight & secure. Ensure that the outgoing cables from the SMDB are terminated in the respective Distribution Boards / equipment. Ensure that the earthing of the SMDB has been completed. Ensure the availability of power supply to the Submain Distribution Board.
Where are the fuses on a SMDB board?
The boards are installed half way through the mains distribution system, generally at the point where a large distribution cable terminates, and several smaller sub-circuits start. The board may be fitted with HRC fuses, MCB’s or MCCB’s. It may hence take the form of a large fuse board or and LV panel board.
What should I do if my SMDB is damaged?
Repair / replace damaged components, if any. Ensure that the SMDB are properly tagged & identified location wise and service wise as specified. Ensure that the wiring termination to the Sub main Distribution Board are complete, tight & secure.
