Wiring
Wiring found in churches and schools is most often constructed with higher capacity wiring and more rugged devices than residential structures. Because churches can accommodate a large number of people, most electrical and life safety codes have special requirements. Generally, these requirements recognize that in an emergency, a high occupancy building will take longer to evacuate than a residence. The plastic-covered cable that is typically used in homes is generally prohibited in places of assembly. Wiring should be metal-encased. While considerably more expensive, this wiring doesn't create as much toxic smoke when it burns, giving extra time to safely evacuate.
