disconnect the supply cable from cu and join the phase and neutral together then go to ur light switch and provided that he circuit is complete with ur bulbs in do a continuity test on the switch cable live in and switch live out these should beep out if the circuit is comple meaning there will be continuity at the switchh cables
You don't megger test continuity. You test for that with a continuity meter or ohmmeter. "Meggers", as they're often called, produce high voltages to test the integrity of a conductor's insulation.
In a lighting circuit an open circuit will turn off the light.
The maximum number of standard lighting outlets on a 20 ampere circuit can vary depending on the wattage of the light fixtures and the local electrical code regulations. In general, as a rule of thumb, you can typically have around 10-13 standard lighting outlets on a 20 ampere circuit.
Lighting is like an electric circuit in that it requires a complete pathway for electricity to flow. Just as a circuit consists of components like a power source, conductors, and a load (like a light bulb), lighting systems depend on a source of electricity, wiring, and fixtures to illuminate a space. When the circuit is closed, electricity flows, allowing the light to operate. If there is a break in the circuit, the flow of electricity stops, and the light goes out.
Lighting circuits (UK) are fused at 15A. If in doubt, check the fuse/MCB. Unless the 7A device is lighting, connecting it would be illegal in the UK. Don't forget anything else on the same circuit.
A continuity test, just turn the lights on and if there is continuity the fixtures will let you know.
To identify a short circuit on a lighting circuit, a continuity test or a resistance test can be performed using a multimeter. This involves measuring the resistance across the circuit; a reading of zero or close to zero ohms indicates a short circuit. Additionally, a circuit breaker or fuse may trip, which can also signal a short circuit condition. Always ensure power is turned off before performing any tests for safety.
A lighting circuit would be a parallel circuit.
To test for earth in a lighting circuit, you can use a multimeter set to measure resistance or continuity. First, ensure the circuit is turned off and isolate the lighting circuit from the power supply. Then, connect one probe of the multimeter to the earth terminal and the other probe to a known earth point, such as a metal part of the fixture or an earth rod. A low resistance reading indicates a good earth connection, while a high or infinite reading suggests a problem with the earthing.
to make sure the protection device such as fuse are connected at the live part

it shows that somewhere on the tail lighting circuit there is some kind of a short circuit,one can test using a multimeter to find the probklem..
Which would be better in lighting a house a closed or an open circuit ?\

Short circuit test and open circuit test are widely used to test the efficiency of the transformer.
To effectively perform track lighting replacement in your home, follow these steps: Turn off the power to the track lighting at the circuit breaker. Remove the old track lighting by unscrewing it from the ceiling. Install the new track lighting by attaching it to the ceiling with screws. Connect the wires of the new track lighting to the existing electrical wiring. Turn the power back on and test the new track lighting to ensure it is working properly.
