CITY OF HOUSTON

ELECTRICAL CODE

 
http://documents.pub...amendments.html
 
301.2 Exempt Work.
Exemption from the permit requirements of this code shall not be deemed to grant authorization for any work to be done in violation of the provisions of this code or any other laws or ordinances. An electrical permit shall not be required for the following:

 

8. Electrical wiring, devices, appliances, apparatus or equipment operating at less than 50 volts and not capable of supplying or controlling more than 50 watts of power.
 

 

That seems to exempt most antenna work from needing a license in Houston, though it makes me wonder about cable TV line amplification, since that has used 60 volts for decades, and some modern cable TV amps use 90 volts.

Then why are the plugs on all the HRs two pronged?

So they are less likely to invite ground loops.

Ground loops are seriously bad business in TV and radio.

If they're anything like jurisdictions around here, they have an entirely separate set of codes for the kinds of things listed in this one.

In my jurisdiction, there are licenses for car stereo installers that are different from home AV installers that are different for those who do satellite installs. TV antenna installs is another license entirely. There's a whole series of different categories under the heading of Low Energy Technicians.

Someone should shoot this thread and put it out of its misery.

 

I agree.  Grounding arguments are a PITA.  Referring to the NEC is like...well, books are written that try to explain the NEC and all its seemingly contradictory information.  Personally, I prefer The Electrician's Handbook, a book that clearly shows what has to be done and how to do it.

That obviously happened because of a failure to ground the thread.

My workplace once had a SOP that contained the statement "excessive redundancy should be avoided", so I assume that a little bit is desirable.

Heh. Just saw a sign at a gas station's car wash: "Pre-pay before you enter"..... Paying before you enter should get the desired effect....

Been meaning to ask you, just out of curiosity, what were you doing that required you to dig into the NEC so much?  I was fortunate enough to ply my trade in a plant that never saw an electrical inspector.  We did have a few licensed electrical contractors that worked with us (or I should say, slept with us) and they never bothered with it much.  We did exceed most Federal standards in our workplace.  Sounds like you were buried in that wretched book for quite some time.

It appears to be happening again.  I just sent a post out and nothing happened.  I was wondering why you spent so much time with the NEC.  Just out of curiosity, what were you doing at the time?

Regrettably, no licensed contractor can hang their hat on The Electrician's Handbook as the be-all and end-all of electrical code.

It's usually used in conjunction with the NEC book.  It doesn't pretend to be the actual code itself.  Ever read it?  There are also a bunch of books that explain the NEC in clear language.  Being a licensed electrician in NJ just means that they passed a test that uses many questions that are NEC based.

If you have to understand a book the NEC is the one you're expected to perform to.

Ever read it?

IIRC, The Electrician's Handbook is for Canada. The American Electrician's Handbook is for the US. I've read neither cover-to-cover.

Being a licensed electrician in NJ just means that they passed a test that uses many questions that are NEC based.

Being an electrician in most US jurisdictions means more than a nodding familiarity with the NEC. There are a few that don't adopt the NEC but they're few and far between.

Of course I meant the American Electrician's Handbook, you can clearly see that I live in NJ.  My God, you can find more things to pick at than a flea bitten basset hound.
