Hi
I have installed a lighting circuit which has emergency with (integral battery packs) and non emergency lights on the same circuit (from the same MCB). The are wired in PVC twin and earth cable.
The British standard for emergency lighting states the following,
IEE Guidance Note 4 refers to BS5266, of which Section 8.2.1 states: ‘Cables used for the connection of an escape lighting luminaire to the standby power supply should…possess inherently high resistance to attack by fire…’. BS5266 also states that PVC cables in trunking (steel or PVC) and PVC/SWA cables will need additional fire protection.
Does the above imply I need extra protection on the PVC cables? If not how can I demonstrate this to a consultant to show how I have complied with the relevant standards and regulations?
