What is a one-way lighting circuit?

• A circuit controlled by multiple switches

• A circuit that only uses 2-core SWA

• A circuit controlled by a single switch and light point

• A timed emergency light circuit

What is the purpose of a two-way lighting circuit?

• To control lights from two different locations

• To link two circuits together

• To power two luminaires in series

• To create emergency override

Where would you typically find a two-way lighting circuit?

• Kitchen ceiling

• Garden lighting

• Top and bottom of a staircase

• Fuse board

What is an intermediate lighting circuit?

• A basic single switch and lamp

• A circuit allowing control from three or more locations

• A circuit using intermediate voltage

• A system with dimmable LED lighting

Which switch type is used in a three-way control lighting circuit?

• Dimmer

• Single pole

• Intermediate switch

• Isolator

What happens if you wire a two-way switch incorrectly?

• Nothing — it still works

• It causes a trip in the consumer unit

• The lights may not switch on or off properly

• The circuit operates faster

Why is it important to identify the correct cable cores in lighting circuits?

• To choose the right colour of switches

• To make the job look tidy

• To ensure correct function and safety

• To lower power consumption

Which regulation requires lighting circuits to be installed safely and comply with disconnection requirements?

• EAWR

• Part L

• BS7671

• PUWER

What is the common method used to wire domestic lighting circuits in the UK?

• Ring final circuit

• Radial final with looping-in method

• Star topology

• Spurred back to back

What is the main benefit of the loop-in method for lighting?

• Easier to install sockets

• Reduces use of conduit

• Fewer junction boxes required

• Works only with metal back boxes
