Sample questions
01What type of cable is typically used for central battery emergency lighting systems?
- AFire-resistant cable
- BAluminium conductor cable
- CStandard PVC insulated cable
- DCoaxial screened cable
Why: Fire-resistant cables are used to ensure circuit integrity during fire conditions.
02Under Approved Document B Volume 2, what is the minimum fire survival classification for emergency lighting cables?
- A90 minutes
- B60 minutes
- C30 minutes
- D15 minutes
Why: Approved Document B Volume 2 para 5.30: cables for a protected circuit that must operate equipment during a fire should achieve PH 30 when tested to BS EN 50200 (incorporating Annex E). Para 5.31 points to BS 5266-1 for large and complex buildings, where a longer survival time may be specified.
03Why is circuit segregation important in emergency lighting systems?
- ATo prevent a single fault from disabling all emergency lighting
- BIt removes the need for any fire-resistant cable on site
- CIt allows a smaller battery capacity to be specified overall
- DIt reduces the total length of the cable that is required on site
Why: Segregation ensures faults do not affect the entire emergency lighting system.
