I Explosion Proof Boxes

Explosion Proof Boxes are enclosed metal boxes that have the ability to contain an explosion.  They are able to keep harmful materials from exiting the box in case of an explosion.  If an explosion does occur, the box will keep flames, gases, and fumes contained within the case..  If these were to leave the case, it could be disastrous to the job site location.

These boxes are made for internal explosions only.  They are not designed to withstand external explosions.

II Explosion Proof Circuit Breaker

A circuit breaker is designed to protect an electrical circuit from damaged caused by a power overload or short circuit.  The circuit breaker works automatically and unlike a fuse has the ability to be reset to resume normal operations.  For hazardous locations the circuit breaker would be housed in an explosion proof box to seal it from the hazards in the area..

III Explosion Proof Motors

An electric motor uses electrical energy to produce mechanical energy.  This energy is used to perform whatever action determined by the rest of the equipment.  For hazardous locations the motor would be housed in an explosion proof box to seal it from the hazards in the area..

IV Explosion Proof Control Panel

A control panel is a flat, usually vertical, piece of equipment where control or monitoring equipment is mounted.  In an explosion proof control panel this equipment is placed within an explosion proof box.  Then average controls are mounted outside the container and the heart of the equipment stays within the explosion proof enclosure.

V Explosion Proof Lighting

Explosion proof lighting is designed to be placed within hazardous locations.  It is much safer than the traditional lighting setups.  Many of these setups include explosion proof switches, outlets, plug-ins, larger glass tubes, and cases.

VI Explosion Proof Distribution Panels

The Distribution Panel is the main electrical control center.  It tends to contain switches or circuit breakers and connects to the service wires and delivers current to the various branch circuits.  It would be housed within an explosion proof box to separate it from any hazardous materials that could be at the location.

VII Explosion Proof Glands

 They are used to firmly secure electrical cable entering a piece of equipment. It provide an explosion proof seal and strain relief between the external and internal surfaces of the equipment.  They are usually configurable to work with any cable within a specified size range.

VIII Explosion Proof Fittings

In locations specified by the NEC (articles 51 through 517) as explosion hazardous, you must install explosion proof fittings.  These fittings can be anything from special seals, switches, convenience outlets, and motor starters.  The exact fittings are determined by the job, function of the machinery, and hazardous material in the area.

IX Type P Cables

Type P Cables are primarily designed for power, control, signal and instrument applications for several industries.  These cables have excellent resistance to oil, abrasion, moisture, sunlight, and ester-based mud.  They are suitable for use in Class 1, Division 1, and Zone 1 applications.  They also meet the crush and impact resistance requirements of UL 2225.
