C&G 2365 Level 2
Sparks Basics · C&G 2365 Units 201–204 · Free course section with an account
The 2365 Level 2 diploma is the standard classroom route into the trade, covering health and safety, electrical science, installation technology and wiring methods. It's a broad syllabus, and cramming it the week before an assessment doesn't stick.
We break the same ground into bite-size lessons with practice questions on a spaced-repetition schedule, so the theory you learned three weeks ago resurfaces right before you'd forget it. Start with the free sections — safety, tools, and circuit fundamentals — and build a daily streak.
Everything is written originally against the regulations and tagged by unit, so what you practise lines up with what your college assesses.

Safe isolation
The procedure that proves a circuit dead before anyone works on it. Prove the voltage indicator against a known source, isolate the circuit, secure the isolation with your own lock and tag, prove the point of work dead across all conductor combinations, then prove the indicator again. The final step is the one that catches a tester that died mid-job.

The earth wire of a circuit. It links the metal parts of the equipment the circuit feeds back to the main earthing terminal. It is not the normal load-current return path, although equipment can produce protective-conductor current in normal operation. During an earth fault it provides a path for fault current, working with the earthing arrangement and protective device to achieve disconnection. In UK wiring it is green and yellow, or bare inside twin-and-earth cable, with green-and-yellow sleeving wherever it is exposed.

The distribution board of a domestic installation. A main switch, residual-current protection and a row of circuit devices on a DIN rail split the incoming supply into individually protected final circuits. Modern UK consumer units sit in non-combustible enclosures and increasingly give every circuit its own RCBO instead of sharing RCDs across banks.

Connecting an installation's exposed metalwork to earth and back to the supply source. That gives fault current a deliberate low-impedance path home, turning a live casing into a large, brief fault current that the protective device can detect and disconnect — without it, the casing simply stays live.
