What is proof load and how it is calculated?
proof load testing is to try to find the % at which the equipment can lift over the safety working load.
What is a vapor tight fixture light?
It is a fixture that has a hermetical seal that keeps fumes and vapours from the electrical parts of the fixture. A good example of a vapour tight fixture is one that is used in paint spray booths. These types of fixtures are not to be confused with explosion proof fixtures which are in a different category altogether.
What are specialized Cables for explosion proof wiring?
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.
Are child proof receptacles required in the new national electrical code?
Yes, they are required by the national electric code.
Can you install a double pole switch in a 120V circuit?
=== === Yes but it is redundant. The only place that you can open the neutral and hot wire at the same time in a North American system is when isolating a load in an explosion proof installation All the rest of the time the neutral remains unswitched. A two pole switch is used on 240 volt loads as code states that both legs must be disconnected from the load. If only one leg is disconnected there will still be a 120 volt potential on the load to ground. As always, if you are in doubt about what to do, the best advice anyone should give you is to call a licensed electrician to advise what work is needed.Before you do any work yourself,on electrical circuits, equipment or appliances,always use a test meter to ensure the circuit is, in fact, de-energized.IF YOU ARE NOT ALREADY SURE YOU CAN DO THIS JOBSAFELY AND COMPETENTLYREFER THIS WORK TO QUALIFIED PROFESSIONALS.
What is the meaning of EEX d II CT4?
It is the explosion protection classification of a piece of (European) equipment which can be used in an explosive atmosphere. EEx d IIC T4 EEx = Explosion proof (certified according to European Standards from series EN 60079 or EN 50xxx) d = flameproof enclosure (see standard EN 60079-1) IIC = device group (Hydrogen) T4 = Temperature calss 4 (max. surface temperature = 135°C)
Can a neutral conductor be broke in a disconnect?
The neutral can be broken in some installations. One example is when wiring explosion proof equipment.
Cost of 1000 gallon propane tank?
It's free! You just have to pay for the explosion proof electrical and vehicle crash protection around it.
What is the definition of explosion proof equipment used on board ships?
Overheating due to overload and subsequent flaming, arcing or burning will liberate explosive gases and vapors gradually, from within the compartment.
Should I have an explosion proof fan in my garage?
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.
How are explosion proof refrigerators manufactured?
Explosion proof refrigerators are manufactured encased in steel. Their cabinet interiors are sparkproof with a non sparking magnetic door gasket with foam in place.
Definition of explosion proof?
resistant to explosions resistant to explosions
How do I capture and filter and pressurize natural gas from a water well for personal home use?
You don't. Leave it to the gas companies to deal with situations like this. The cost for you to do this safely would be astronomical in regards to the electrical equipment you would have to purchase. The electrical component gets into an explosion proof category. All compressor motors have to be explosion proof. Switches and controls also fall under the same regulations. For example one switch alone with its enclosure may well cost you 350 dollars. Motors in the thousands of dollars. The money that you would have to put into such a venture, you would never break even. Ten years down the road it would still be cheaper buying from the gas company.
Are LED lights explosion proof?
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.
Do you have to hook up a ground wire to a tamper proof outlet?
Yes, you can still have an electrical fault current on an appliance or the wiring which needs to have a ground return path for personal and equipment safety.
What are the special cables required for explosion proof wiring?
I thnk...it cn b ZHFR,FLR cables r suitble for explosion free wiring
What is difference between IP degree of protection and EEX explosion proof?
IP stands for ingress protection. This rating pertains to what size of particle or type and type/strength of water/liquid immersion and duration of exposure an equipment enclosure can be subjected to prior to being compromised. EEX refers to a level of an equipment enclosure being 'explosion proof'. The key to this distinction is that equipment that is rated as explosion proof has some method of suppressing sparks or otherwise cooling any process contained in it to ensure that any flamable gas in the environment outside is not ignited. Flamable gas that is in the enclosure may ignite but the EEX enclosure prevents that flame/heat from affecting any flamable gas outside. This is not so with IP ratings. IP ratings are not concerned with temperature/sparking/flashpoints but with excluding dirt, dust, vapor and water. Something may be IP rated and not EEX rated; conversely, something EEX is usually IP rated.
