I thnk...it cn b ZHFR,FLR cables r suitble for explosion free wiring
The neutral can be broken in some installations. One example is when wiring explosion proof equipment.
Cables usually aren't the problem for explosion proof electrics and electronics. Switches, (motor/generator)brushes, breakers and relays are a (much) bigger issue. Followed by things using, or emitting electro-magnetic radiation. I assume, if you want to be thorough, one could use cables with a higher insulation/shielding rating for further protection in an explosion-prone environment.
It is imperative to use an explosion proof fan when working with flammable objects as the littlest spark or even heat build up in the fan could cause an explosion. While explosion proof fans are more expensive than their non-explosive counterparts, however, the safety they provide is worth every penny.
Explosion proof refrigerators are manufactured encased in steel. Their cabinet interiors are sparkproof with a non sparking magnetic door gasket with foam in place.
yes
resistant to explosions resistant to explosions
No. Household wiring requires household wiring.
LEDs are not automatically explosion-proof. It would depends on the design as a whole. what type of switch that's used, how well it's encased, amount of current running through it, etc.
Coherence.
Theorems are statements in geometry that require proof.
Anything that requires experiments that requires proof or to gain a Value of something.
