Increased safety enclosures, also referred to as: increased safety junction boxes, are stainless steel (or GRP materials) enclosures designed to prevent the possibility of excessive heat, the ingress of water or dust, as well as being impact resistant, thereby providing a safety factor against breakdown. These hardened boxes are intended to house electrical equipment which will not generate an arc or spark during normal operation, and are suitable for use in Zone 1 or Zone 2 hazardous locations.
