I AM IN AIR CONDITIONING WHICH DEALS ALOT WITH ELECTRICAL WIRING. WHEN REPLACING AN AIR CONDITIONER (A 5 TON ROOF TOP UNIT) WITH A NEW DISCONNECT WHERE DOES THE NEC STOP ME AND REQUIRE AN ELECTRICIAN IN THE INSTALATION. I WOULD ALSO LIKE THE CODE NUMBER IF ANYONE KNOWS?
 
Re: WHERE TO DRAW THE LINE

This is not a code issue, but a licensing issue. Check with your local building department or with your state professional licensing board to find out exactly what the scope of work you are permitted to do without an electrical license.

Very few places would give you a hard time over changing the box.Now if your changing the amps to something higher or replacing the cable feeding it ,then there might be a need for permit and electrician.
But NEC does not deal with license
 
Re: WHERE TO DRAW THE LINE

We are having a huge problem here with the HVAC guys trying to do our work. As far as I am concerned only a licensed electrican should change the disconnect period. Here you have to pull 2 permits for that type of work one for the AC unit and one for the electrical.

Highkvoltage, unless the A/C contractor holds an active EC license here, it is the same as it is in your area.

HVAC guys can't touch electrical here, either. The ones who are doing what they are supposed to sub out the electrical and make sure a mechanical permit gets pulled for the heating or A/C and an electrical permit gets pulled for the wiring.
 
Re: WHERE TO DRAW THE LINE

Would we take this a bit further and not allow plumbers to unwire and rewire a replacment water heater ? Could they change the heating element ? Do we make them pull 2 permits ?
 
Re: WHERE TO DRAW THE LINE

Many areas don't require a permit to be pulled if the repairs is under a certain amount like $500.00 for Indiana so if the home owner buys the water heater and the plumber only charges $499.99 to install it guess what.

Jim, it doesn't matter what "we" would allow, it is up to the local codes, laws, and the AHJ.

Re: WHERE TO DRAW THE LINE

jim. So while I'm installing the disconnect and I'm there I should just install the AC unit. It's the same thing each trade should stay in their expertise. :confused:
 
Re: WHERE TO DRAW THE LINE

Here in California, a contractor may perform work outside of his trade if the work in question is both "incidental and supplemental" to his own work.

Of course that's open to interpretation, from what I've see this state usually allows the HVAC tech to work on any electrical EQ from the load side of the disconnect in, but not the disco itself. Internal fuses, contactors, are fair game.

We also have a big problem here with residential HVAC guys thinking this allows them to run their own circuits, which it does not. Last year I went to court along with a customer to testify on just such an installation. The HVAC contractor who refused arbitration because he was sure he was in the right, ended up paying for the entire cost of the repair (this genius had tapped a dryer circuit in the attic to feed the condensing section, nice.).

Best bet if you're not sure is to check with your AHJ.
 
Re: WHERE TO DRAW THE LINE

Many counties do not even require a permit to change the water heater.This is in hopes that at least the home owner hires a plumber.Should they complicate this job with 1 or 2 permits the cost of the job gets so high that the handyman ends up getting the job.Pulling a permit sometimes could take more time than the actual job.What do most of you charge for your time to pull a permit ? This could take 2 trips just over the permit.
 
Re: WHERE TO DRAW THE LINE

As has been pointed out this is entirely up to each locality.

In my area oil burner technicians, plumbers and other HVAC technicians can work on the load side of the equipment disconnect.

I was just at a large plumbing supply house and noticed they had an area dedicated to selling electrical supplies, boxes, flex, wire, switches connectors etc.

I have never seen a plumbing section at the electrical supply house. :confused:
 
Re: WHERE TO DRAW THE LINE

Right now, I would like to see the A/C guys be FORCED to do the electrical connections to their units.
The situation is as folloiws: The Roof Top Units are mounted on the roof and they have two ducts extending straight down about 15 feet. In between the two duct is where the electrical connections are supposed to go. Due to the presence of sprinkler pipes, walls, etc., this is no longer accessable. This should have been coordinated better, I know. If the tin knockers were responsible for connecting their own units, they would quickly learn to sychronize things.
