An Electrical Safety Certificate is a document that is issued after an electrical installation has been inspected and tested, confirming that it meets the legal requirements for safety.

An Electrical Installation Condition Report (EICR) is a more detailed report of the condition of an electrical installation, including a list of any defects or deficiencies and recommendations for remedial action. A Periodic Inspection Report (PIR) is a summary of the results of a periodic inspection of an electrical installation, with any defects or deficiencies listed and recommendations for remedial action.

An electrical installation must comply with the applicable regulations and standards, be properly maintained and inspected at least every five years, and be regularly tested for electrical safety.

The minimum safety distance between electrical cables and other objects is determined by the type of cable and the voltage of the system. The minimum safety distance for low voltage systems is typically 50mm.

A Residual Current Device (RCD) is used to provide additional protection from electric shock by automatically disconnecting the electrical circuit in the event of an earth fault.

An arc fault circuit interrupter (AFCI) is designed to detect and interrupt an arc fault, which is caused by a damaged electrical wire or connection and can cause a fire.

An overcurrent protection device is used to prevent damage to electrical equipment by automatically disconnecting the circuit in the event of an overcurrent.

A fuse is a one-time-use device that is designed to be replaced after it has blown, while a circuit breaker is a reusable device that can be reset after it has tripped.

The minimum spacing between live parts and protective earth is determined by the type and voltage of the system. Generally, the minimum spacing for low-voltage systems is 6mm.

An Earth Leakage Circuit Breaker (ELCB) is designed to detect and interrupt an earth leakage, which is caused by current flowing through an unintended path and can cause a shock.

A Voltage Indicator is used to indicate the presence of live electricity.

A voltage tester is used to measure the voltage of an electrical circuit.

A continuity tester is used to check the electrical continuity of a circuit by measuring the resistance.

An insulation resistance tester is used to check the insulation of an electrical circuit by measuring the resistance between the conductors and the earth.

A clamp meter is used to measure the current in an electrical circuit without the need to break the circuit.

A non-contact voltage tester is used to detect the presence of live electricity without making contact with the circuit.

The maximum temperature for cables installed in walls and ceilings is 90°C.

The minimum bending radius for cables is determined by the type of cable and the voltage of the system. Generally, the minimum bending radius for low-voltage cables is 6 times the overall diameter of the cable.

The maximum allowable voltage drop in an electrical circuit is determined by the type of circuit and the type of load. Generally, the maximum allowable voltage drop for a lighting circuit is 10%.

A voltage drop calculator is used to calculate the voltage drop in an electrical circuit.

A ground fault circuit interrupter (GFCI) is designed to detect and interrupt ground faults, which are caused by current flowing through an unintended path and can cause an electric shock.

A Class 1 circuit is a circuit that is connected to a protective earth and is designed to prevent electric shock, while a Class 2 circuit is a circuit that is not connected to a protective earth and is designed to reduce the risk of electric shock.

An RCD tester is used to test the functionality of a Residual Current Device.

A PAT (Portable Appliance Testing) tester is used to test the safety of electrical appliances for use in the workplace.

A voltage detector is used to detect the presence of live electricity without making contact with the circuit.
