I have electical books but am confused.
Please may I beg your advice regarding the following difficulties:
I am wondering the simplest way to wire a 3 way switch when the circuit may need to continue on to other lights or fixtures or perhaps a better way to plan this circuit.
ex: My electrician currently has it planned in my NEW SHOP CONSTRUCTION
- to go 12/2wg from the MAIN PANEL BOX to a JUNCTION BOX
- then splice and continue 12/2wg to the 1st-3Wswitch
- then continue with 12/3wg to the 1st light -
- then continue with 12/3wg to the 2nd light
- then continue with 12/3wg to the 2nd-3Wswitch
- and terminate.
At the JUNCTION BOX, he has brought in another 12/2wg going to a single pole light switch that then continues to a bathroom light and then terminates.
At the JUNCTION BOX, he has also brought in another 12/2wg going to a attic pull chain light and then terminates.
What I gather is that somehow he intends to use the 12/2wg that is coming from the MAIN PANEL BOX to splice into all of the above connections to make them hot in the one JUNCTION BOX. That seems like way to many cables being spliced together for one thing and way to many wires overall in the box also.
I have been assured that the JUNCTION BOX is perfectly fine within code and that it is sitting on top of a 2x4 in the attic floor and will be reasonably accessible from the shop side of the attic if needed in the future.
I am not sure if the 3W switch configuration will work in its present plan.
No part of this makes me feel comfortable but I am at a brick wall with trying to explain why I don't believe that this is the best or most correct way to do things even if code will allow it.
Nor am I experienced enough to know exactly how or if the JUNCTION BOX is:
- simply another point of failure opportunity or
- if it poses a significant fire hazard risk or
- troubleshooting risk in the event of something not working in the future
- who is going to know or remember it is there?.
The rationale I've been given is that I saved wire and I saved having multiple connections within the easily crowded smaller switch or light boxes and its done and its not going to be changed..... Is a junction box in new construction a standard business practice or a standard no-no. He also has 2 other JUNCTION BOXES planned in my family room again to save wire runs from switches to lights & fan. As best I can see it, I have a brick wall short of tearing it out myself and redoing it or calling another electrician which I can't really manage at this time. I easily have several extra rolls 12/2wg sheathed electrical cable available.
Surely there is a better way to connect the two 3W switches and the associated two lights. And perhaps have other things also on the circuit past this complexity or before this. Surely having several JUNCTION BOXES sitting around my attic is not appropriate business practice. Am I just overly biased against JUNCTION BOXES or is this a valid concern?
I thank you for any consideration you can give this matter in giving a reply.
