Terminology

Is this homework, because it looks like homework and we don't do peoples homework here.

See previous threads on CR4 as these questions have be answered before. Also a simple google or Wikipedia search will give you the results also. For basic differences consult an online dictionary as the names clearly indicate the differences.

What makes you feel it is home work?

I spent lot of times to find the correct answer for the differences – no success. Can you mention some specific web site where it is answered.

What makes you feel it is home work?

The way the question was asked and formatted, the nature of question and the similarity to previous homework questions asked on CR4.

Can you mention some specific web site where it is answered

http://en.wikipedia.org/wiki/Main_Page

http://www.merriam-webster.com/

These are really good places to start (as mentioned in post #1).

Please

- Don't under estimate other people.

- Don't think the Dictionary or Google or Wikipedia search gives you everything you need to know. If it is, then people didn't go to school or post questions in this type of forums. Before sending this website, did you ever try all the terminology (these are 100% electrical engineering terminology) and get the correct answer?

- If you don't know the answer, stay away. No body pushes you to respond.

I am assuming you are the original poster of the topic (correct me if I am wrong).

What are the basic the differences between the terms

As answered in post #1 and post #4 the BASIC differences are clearly explained on both Wikipedia and the online dictionary.

What exactly do you want if not the basic differences between the five that you specifically asked for? If you want more detailed information please provide a more detailed explanation on exactly what you want and your application!

- Don't think the Dictionary or Google or Wikipedia search gives you everything you need to know.

But it DOES give a clear explanation on the BASIC differences, which was what the original question and the followup post #2 specifically asked for.

- If you don't know the answer, stay away. No body pushes you to respond.

Being that I work in these areas certifying hazardous area equipment and selling fire resistant foam and materials I do actually know what I am talking about.

- If you don't know the answer, stay away. No body pushes you to respond.

If you are not the original Guest poster I find this statement rather ironic as I have already answered the question based on the available information given by the original Guest, where as you have not bothered to try and answer the question yourself.

Dictionaries will do what you ask, you failed to supply any context (other than posting in an EE forum).

All these terminology are general terminology. I am sure everyone, even student in school can understand it. As an electrical or an engineer it should not be difficulty to understand these terminology.

Please check in the dictionaries I am sure you can find it there.

I cannot give you the differences as I am writing from memory and I do not have any imformation material with me.In electrical fittings such as light fitting,socket outlet fitting,LV distribution board,one may come across "explosion-proof" specification.This may be used in high risk area such as oil rig,refinary or chemical plants.Flame-proof is lower spec than explosion-proof thus cheaper which are installed in tunnels for trafic or data/communication cables.They are many times more expensive than normal industrial electrical fittings and they comply to some IEC standards, in enclsure and the ability to contain the explosion or flame in the fittings when it ever happens.You may try searching in a French manufacturer's site, Legrand for these actual models.I think there is no fire-proof fittings.

Fire resistance and retardant refer to electrical parts or material that can perform that duty.For example,fire resistant cables are used in the essential circuit between the generators and the emmergency main switchboard and out going feeder cables that continue to supply power to the fireman lifts,lightings and smoke spill fans to povide smokefree air in fire escape stair wells during fire in highrise buldings.With the help of fire doors,this critical time,about 1 hour, for people to escape is made available.I could not understand why the recuers and those who escape during Sept-11 attack on twin tower in America,were saying that it was dark or poor vissibility while climbing down.Please check commercial available "Radox fire resistance cable", "MICC cable -- mineral insulated copper covered cable"and retardant used in "Frans transfo,Trihal cast resin transformers".

I know - I know.

They are all spelled differently!

Did I get your homework done for you pretty little thing?

General dictionary searches or wiki summaries may not be what is needed. Various electrical codes or testing agencies may have specialized definitions, and there may be other regulatory specifics. For sure check the NEC (National Electrical Code), and perhaps some UL literature.
