Junction boxes

Steve, in general, you can put as many j-boxes as you want. The NEC does not restrict that.

Are you currently in OJT or some sort of apprentice program? Are you taking classes? Are you studying the code? Do you work with competent electricians who are training you?

I agree. But who is Steve?

Brad is an ?EIT,? an, ?Engineer In Training.?

Steve? Good question. Peripheral vision sometimes results in fooled perception. Engineer in Training? Never heard of such a thing. What exactly is that? Someone who has comp[leted a four-year degree and is now out on the job learning what being an engineer is? Or is it a first year college student? Or is it someone strictly learning on the job with no college?
 
EIT might be a term that we picked up here in Florida. I have a BS in Electrical Engineering and passed my Fundamentals Exam (FE) and studying the code to take my Professional Engineers Exam which won't happen til 2010. I am currently working for a small firm with me being the only Electrical Designer and my boss is the PE. He sometimes isn't available for me to talk to due to meetings and such, so instead of sitting around waiting for him I found you guys :grin: .
 
Hey Brad:

Thanks for clueing me in on your status. Sounds like you are going about things the proper way. The forum can be a big help, that is for sure.

Please excuse my prior demeanor, I assumed you were some green electrician-wanna-be who was actually out there installing jobs and doing stuff without proper knowledge.:cool:

So, any questions you have, fire away!:)
 
:grin:

thanks. I have been searching through the boards for a while now. I try to use the search feature before i post something, but the site has helped me a lot so far.
 
Even if you post a question that has been asked before, that is okay. Like I said, I just sometimes take exception to someone who jumps into "I am an electrician" and starts doing installations on their own without adequate knowledge. Obviously this does not apply to you.:)

Also, I am looking forward to you getting in on the discussions and hearing your two-cents worth!

Is there a maximum number of junction boxes allowed on a circuit run? or is the box fill the only thing I would need to worry about?

Thanks

There is no maximum, at least for code purposes.

As a practical matter, it sometimes simplfies conduit runs to add junction boxes along the way.
 
I think that ?EIT? is a term that is being replaced, or in some places has already been replaced, by ?PEI,? ?Professional Engineer Intern.? Becoming licensed as a Professional Engineer is generally a four step process. First, you need a qualifying degree from an accredited institution. Secondly, you need to pass the ?Fundamentals of Engineering Exam.? You can usually (and should, if at all possible) take this test while still in college, while the information covered in the exam is still relatively fresh in your mind. This eight hour exam covers a wide spectrum of topics, from basic math to basic science (e.g., chemistry and physics) to basic engineering (e.g., statics, dynamics, electrical, structural, and materials). When I took my exam, I had to answer 240 questions in the morning session (which allowed one minute for each question) and 120 questions in the afternoon session (two minutes per question).

Next, you need to have some years of experience (generally four or five, depending on the state in which you live), under the supervision of a PE. Finally, you need to pass the ?Principles and Practices of Engineering Exam.? This too is an eight hour exam, but it covers fewer topics (i.e., it emphasizes the area of your specialty, such as electrical power, electrical controls, mechanical piping, mechanical systems, structures, or civil engineering). It also has fewer questions that, naturally, take longer to answer. When I took my exam, I had to answer 4 questions in the morning session, and 4 more in the afternoon session, so I had one hour to answer each question.

When you successfully get through all of this, the state will issue you a license, and you can officially advertise your services as a Professional Engineer. That gives you the right to sign and seal and formally issue design documents. When you issue such documents, your seal and signature are attesting to the work having been done by yourself, or under your supervision. That assures the public that should anything go wrong (heaven forbid), there will be no quibbling over who is responsible for having issued the design.

Here is a phrase that is said to be unique in that it applies to all situations and for all time: "This, too, shall pass."
 
consider this situation: You have to run a length of conduit and, due to a defunct supply chain, you are totally out of couplings. However you have plenty of boxes and connectors. So you run a stick, add a connector, box and another coupling, another stick of EMT and so on.
Thus a fifty foot run would consume four extra boxes and eight extra connectors. However this saves the vast expense of another box of couplings because "it's not in the budget."
The low-brain powered apprentice [sometimes journeyman] will pull wire from box to box and make up in each box. The ground, green wire will not be bonded to any of these boxes. Code? What Code?
At the end, there will be one less cover plate available. This will not be noticed until the day of the final inspection. In which approval from the office for the purchase of one blank plate will not be granted until it is reluctantly discovered that there will be no final check until the certificate of occupancy is granted. And there will be a re-inspection fee.
But remember, there was the savings of a box of couplings.
As to the original question, there is no limit to the amount of boxes in a run. Keep your troops supplied.

Wow. I heard people did business that way.:-?

As for the J-boxes, if you use one every 24" you can use the 60% fill column for your conduit.:)
 
Are you only willing to give info to non-wanna-be-electricians? That doesn't sound very friendly to me... It seems anyone should be given the same info no matter what there wanna-be status. I would like to preserve life and limb no matter what the protocol is... maybe some think otherwise.
