PVC Casing-Capping Wiring Materials Quiz

PVC Casing-Capping Wiring

• PVC casing-capping wiring is also known as surface wiring.
• Materials like metallic conduit are NOT required for PVC casing-capping wiring.
• Casing and capping cover wires for protection and aesthetics.

Miniature Circuit Breaker (MCB)

• MCBs serve to protect electrical circuits from overload and short circuits, ensuring safety in new constructions.
• They automatically switch off circuits in case of faults, preventing damage.

ICTP (Iron Clad Triple Pole) Switch

• Designed for controlling electrical power supply, the ICTP switch is robust and suitable for high-load applications.
• Provides isolation for electrical circuits and enhances safety.

Old Fashioned Wiring

• The type of wiring considered old fashioned is Imperfect (or traditional) wiring, which lacks safety features and efficiency compared to modern solutions.

Distribution Board

• The distribution board is used to distribute electrical power to different circuits within a building.
• It houses protection devices like circuit breakers and fuses, ensuring efficient circuit management.

Plugs and Socket Outlets

• Plugs and socket outlets facilitate the connection of electrical devices to the power supply.
• They provide a convenient way to power appliances and tools.

Fuses in an Electrical Circuit

• Fuses protect electrical circuits by breaking the connection if excessive current flows, preventing potential hazards like fires.

Rewirable Fuse

• The fuse element in a rewirable fuse melts under excessive current, interrupting the flow and protecting the circuit.
• Rewirable fuses are still common due to ease of replacement and cost effectiveness.

Disadvantages of Rewirable Fuses

• One disadvantage of rewirable fuses is their slower response to short circuits compared to MCBs.

Fusing Factor

• The fusing factor represents the ratio of the breaking capacity to the normal current rating of a fuse, indicating its reliability.

Time for Blowing Out of a Fuse

• The time to blow out a fuse is determined by the amount and duration of excess current flowing through it.

High Breaking Capacity (HBC) Fuses

• High breaking capacity fuses are designed to interrupt high fault currents safely, enhancing electrical safety in systems.

Non-Disadvantages of Rewirable Fuses

• A non-disadvantage of rewirable fuses is their simplicity, which makes them easy to understand and use for basic applications.
