Level of interior fire protection, fire resistance duration of at least 30/90 min. These include switches, circuit breakers, wiring, and other pieces of equipment. Their primary purpose is to contain a fire, both within and outside the enclosure, long enough to maintain the. The requirements are thus appropriately high and require comprehensive knowl-edge of fire creation, fire behaviour and fire avoidance as well as the range of options to limit or prevent the spread of fire. How does a fire occur? Often, it is just carelessness – a forgotten candle, an unextinguished. With the introduction of the 15th Edition of the IEE Wiring Regulations in 1981 the UK aligned the requirements of the regu...
