Conduit vs Direct Wire....why


Some parts of the USA require the use of conduit and others don't. Why the differences across the country? Is one superior over the other or just more work for electricians and less work for DIY'ers?

Conduit vs Direct Wire....why


Some areas have very strong unions and corrupt politicians.

I was not trying to say that there are not legitimate reasons and uses for conduit.

My point was the requirement to use conduit in residential wiring instead of metal or plastic sheathed cables.

your point as I read it was there is no reason to use it other than those damn unions and the crooked politicians (I guess they must be in bed with the unions).


Can you say that conduit is not a superior system? If it is, what is wrong with some area that requires the electrical installations meet the highest standards rather than accepting a functional yet inferior system?

Your words not mine (but I do agree with you).

Certainly there are valid reasons for use of conduit, but metal or plastic sheathed cable has been a proven product for many years. Economics is a factor and without a doubt has priced people out of market when politicians require residential wiring in conuit installed by a fraternal group of electricians. The same fraternal group who donated $$$ to his reelection campaign.

By your reasoning: If the best possible should be the requirement for all:

Hard metal conduit is better than metal tubing (EMT)
Threaded joints are better than compression fittings.

All houses must be wires with rigid metal conduit with threaded fitting.

It does not matter what it costs it is the best and safest.

Metallic conduit has been required in the Chicago area a long, long time before certain people were elected. Someone in SC should be careful about accusing others of having corrupt politicians.

to whose re-election campaign? Conduit has been required for a long time in Chicago. They have had 18 different mayors since 1900. I don't know when Chicago first started requiring conduit but I am sure it wasn't enacted after RM Daley has been elected so now there must be multiple crooked mayors allowing this horrible condition to continue.

why don't you find out when conduit was first required in Chicago residential buildings so we know when the corruption in their government started.

Conduit is certainly a superior system, but there is a point where superior becomes absurd.
IMO requiring ALL conduit with limited sections of metallic flex, in a typical residential installation, is 100% certifiably absurd!

Why not require gold conductors that are two sizes oversized to prevent overheated circuits? Hell, the NEC is a minimum standard, right?

Superior by what standard or metric? NM cable could be superior to conduit, depending on your paradigm or needs.

Superior in terms of durability and replacement of conductors.

NOT superior in terms of changes and additions as some would suggest.

I do a lot of things above and beyond code requirements because I believe the code doesn't go far enough. Without knowing why Chicago requires conduit, it is very difficult to argue their reasoning is flawed.

Heck, the code doesn't even require upsizing conductors for voltage drop but every electrician I know does it. So, are we wrong for upsizing conductors?

Unless somebody can find when conduit was first required (in Chicago code) and some discussion as to why, I don't think an answer will ever be realized here.

really? Please list some claim NM has as being superior to conduit and separate conductors with any of a dozen different types of insulation.

Everyone is free to state their opinion on the issue here, but please refrain from jumping on those that don't agree with your opinion. You can make your case more effectively by stating the facts as opposed to challenging others.

Cost? Ease of use? Conductors are already placed in the sheath, versus pulling conductors through a pipe? NM can be used with plastic boxes? NM doesn't have to look pretty because its always hidden? With NM you don't have to make bends at various degrees? An entire cable can be cut with a pair of dikes, vs. cutting conduit which requires a saw or tubing cutter? Conduit has to be measured precisely where NM only has to be close.

All I was saying was that 'superior' was loosely defined.
