Learn DC Distribution Board Wiring

Hi,

In this training I have explained complete drawings of DC Distribution Circuit.

I have covered following topics.

* Understanding Scheme with two incomer

* Understanding Legends

* Basic Idea of DCDB

* Understanding Single Line Diagram of DCDB

* Function of DCDB

* Automatic & Manual Operation of DCDB

* Logic Table for Automatic Operation  of DCDB

* Explained DCDB Circuit design for implementation of logic table

* Explained what will happen if one of the Incomer Trips

* What is function of Bus Coupler

* Explain MCCB UVT Relay

* Voltage Supervision of DC Supply

* How DCDB interlocking works

*DCDB Heater & Fan Circuit

*DCDB Annunciator Circuit

* Lamp Test scheme explained

*Incoming & Outgoing MCB

* Hotter Circuit Explained

* Acknowledge, Reset explained

DCDB drawings are best for someone who start to learn drawings and I will really recommend this training.

Electrical wiring is an electrical installation of cabling and associated devices such as switches, distribution boards, sockets, and light fittings in a structure.

Wiring is subject to safety standards for design and installation. Allowable wire and cable types and sizes are specified according to the circuit operating voltage and electric current capability, with further restrictions on the environmental conditions, such as ambient temperature range, moisture levels, and exposure to sunlight and chemicals.

Associated circuit protection, control and distribution devices within a building's wiring system are subject to voltage, current and functional specification. Wiring safety codes vary by locality, country or region. The International Electrotechnical Commission (IEC) is attempting to harmonise wiring standards amongst member countries, but significant variations in design and installation requirements still exist.
