How To Install Explosion-Proof Lights

Explosion-proof lights, a term unfamiliar to many, are rarely encountered in everyday home life. These specialized lights are primarily used in industrial settings, such as oil depots and chemical plants, where flammable and explosive materials are present. The installation of explosion-proof lights differs from standard bulbs, and there are specific considerations to keep in mind during their use. Today, let’s discuss these aspects.

Before installing an explosion-proof light, verify details from the nameplate and manual: the type, category, level, group of explosion-proof, protection level of the casing, installation method, and requirements for fastening hardware. Ensure the light is securely fixed, with bolts and spring washers intact. Seals for dust and water resistance must be correctly placed. The cable entry must tightly fit the sealing gasket, be round and free of defects. Unused entries must be sealed according to the explosion-proof type, with tightening nuts.

Installation Methods:

Wall-Mounting:

Mount the light on a wall or support (ensuring the shading board is above the bulb), thread the cable through the joint, gasket, sealing ring to the junction box, leaving enough length for wiring, then tighten the joint and fixing screws.

Sloping Rod Suspension:

Pass the joint through the cable, screw it into the steel pipe, tighten the fixing screws, thread the cable through the gasket and sealing ring to the junction box, leave enough cable for wiring, screw the light into the joint ensuring the junction box is facing downwards. Adjust the copper joint and steel pipe to position the shading board above the bulb, then tighten the fixing screws.

Vertical Rod Suspension:

Similar to the sloping rod method, but with vertical positioning of the rod.

Ceiling Mounting:

Screw a 3/4 inch conversion joint into a pendant conversion joint, then thread the cable through, mount it on the ceiling, and follow the same cable threading and tightening procedures as before.

Installation Steps:

1. Identify the location and measure the distance from the light to the power source. Prepare a three-core cable of appropriate length, ensuring it’s longer than the distance.

2. Connect the wires by opening the light’s rear cover, threading one end of the cable, and connecting the live, neutral, and ground wires. Distinguish between neutral and ground for safety. After connections, secure the cable with special tools and close the light cover.

3. Test the light by briefly connecting it to the power source. If the light doesn’t light up within 5 seconds, disconnect and recheck the wiring.

These guidelines aim to provide a basic understanding of installing explosion-proof lights safely and correctly.
