Trinidad and Tobago Electrical Wiring Code

Legal document outlining the regulations for electrical wiring in Trinidad and Tobago.

Ampacity

The maximum current, in amperes, that a conductor can carry continuously without exceeding its temperature rating.

Grounding Conductor

Conductor used to connect equipment to grounding electrodes to ensure electrical safety.

Neutral Conductor

A conductor grounded at the service equipment that carries unbalanced current in a circuit.

Electrical Inspectorate Division

Branch responsible for the inspection and certification of electrical works in Trinidad and Tobago.

Current-Permit

Written permission from the inspection department indicating electric energy may be supplied to a specific installation.

Accessible

Capable of being removed or exposed without damaging the building structure.

Guarded

Protected by suitable covers, casings, barriers, or screens to prevent contact with dangerous points.

Special Permission

Written consent from the authority having jurisdiction regarding certain code interpretations.

Conductors

Wires used for transmitting electrical current.

Incandescent Lamp

A type of electric lamp that produces light by heating a filament.

Fluorescent Lamp

A gas-discharge lamp that produces light by exciting mercury vapor to emit ultraviolet light.

High Intensity Discharge (HID) Lamp

A type of lamp that produces light by creating an electric arc between tungsten electrodes housed inside a translucent or clear envelope.

Light Emitting Diode (LED)

A semiconductor device that emits light when current flows through it.

Electrical Load

The total power consumed by electrical devices connected to a circuit.

GFCI (Ground Fault Circuit Interrupter)

A device that cuts off electrical power when it detects a ground fault.

AFCI (Arc Fault Circuit Interrupter)

A device designed to prevent electrical fires by detecting unintended arcing in a circuit.

Bonding Conductor

A conductor that ensures electrical continuity and conductivity between metal parts.

Service Entrance

The point at which electrical power enters a building.

Wiring Method

The specific technique used for installing electrical wires and cables.

Voltage Drop

The reduction in voltage in the electrical circuit between the source and the load.

Code Compliance

Adherence to the standards and regulations set forth in the electrical wiring code.
