FAQ

Q1: What are the principle of explosion-proof terminal boxes?
A1: Based on two main types:
Flameproof (Ex d): Most common. Uses precision gaps at joints to cool flames and reduce pressure during internal explosions.
Increased Safety (Ex e): Prevents arcs/sparks via enhanced insulation and electrical clearances during normal operation.
Q2: Are the terminal boxes need regular maintenance ?
A2: Yes. Critical checks include: Inspecting flameproof surfaces for damage; Ensuring tight fasteners and intact seals; Replacing damaged parts with certified components. Damaged parts must be replaced with original factory or certified spare parts. After maintenance, its original explosion-proof performance and protection grade must be restored.
Q3: Can internal wiring be connected carelessly after installing the ex terminal boxes?
A3: Absolutely not! The box only provides “containment.” The internal electrical connections must comply with electrical standards, and all other equipment in the circuit (such as installation switches) must also be explosion-proof.
Q4: Is it fully waterproof/dustproof?
A4: Depends on its IP rating. Typical boxes (such as IP66/67) resist powerful water jets or temporary immersion for reliable protection.
