Can standard electrical switches be used on explosion proof trucks?
Yes. Through the use of intrinsically safe circuits, standard off the shelf electrical switches can be used in hazardous areas. By definition, intrinsic safety is an explosion protection technique applied to electrical equipment and wiring intended for installation in hazardous locations. The technique is based upon limiting both electrical and thermal energy to levels which are incapable of igniting a hazardous mixture which is present in its most easily ignitable concentration.
