Panel board capacity refers to the maximum electrical load it can handle safely and efficiently.

• Common capacities range from 100A to 4000A, depending on application.

• Residential panel boards typically have capacities of 100A or 200A.

• Commercial buildings may use panel boards rated from 400A to 1200A.

• Industrial applications can require panel boards with capacities exceeding 4000A.

• Example: A 200A panel board can support multiple circuits for lighting and outlets in a home.

Cables are classified into various types based on their construction, application, and insulation materials.

• 1. Power Cables: Used for electrical power transmission (e.g., XLPE cables).

• 2. Control Cables: For control circuits (e.g., PVC insulated control cables).

• 3. Communication Cables: For data transmission (e.g., coaxial cables, fiber optic cables).

• 4. Instrumentation Cables: For connecting instruments (e.g., shielded twisted pair cables).

• 5. Specialty Cables: Designed for spec...read more

Cable laying involves the installation of electrical cables for power distribution, communication, or data transmission.

• Cable laying can be done underground, overhead, or underwater depending on the application.
