Beyond that it's up to you what you can do about it. Location Miami Fla. Occupation 60 yr old tool twisting electrician. Click to expand Thats the short answer. If OP was feeding 8 small V motors that draw 5A each, would he still be in violation?
Jim W in Tampa Senior Member. Location Tampa Florida. Senior Member. Not so fast ,.. Have a discussion with the super and express your concern. Number of current carrying conductors?
EMT or 6? Location Illinois Occupation retired electrician. And what happens if the 8 V circuits are in the form of 4 MWBCs, with 8 hots and 4 neutrals in the pipe?
I would like to pull a few extra for future use too. I would also need a few neutrals and atleast a ground in there too. Tags: circuits. Now I'm going to assume that you are running this underground since you're using pvc. You must de-rate to run this number of conductors, then you need a pull box to split things at the other end, not worth the hassles. Just run a sub -panel. If my assumption about the underground is wrong, forget the pvc and use emt unless it needs to be rigid.
Comment Post Cancel. You have to figure out exactly what you want, then you can figure your pipe size. What are you feeding? How long is the run?
Is it 3-phase or single phase? The pool pump or shed could have a different voltage , i. Sign up to join this community. The best answers are voted up and rise to the top. Stack Overflow for Teams — Collaborate and share knowledge with a private group.

Is routing a single circuit from the house to a subpanel in the pool shed, then routing a branch back from the pool shed to the pool filter not an option?
It is. I was hoping to avoid the cost of the extra materials for the sub panel. My initial thought was a 30 amp sub panel. What loads are you running in the gazebo and pool shed? The pool filter largest load. The shed and gazebo have lights and receptacles. Reaction score 5, You can, without doubt, have more than one single phase circuit in a containment system. I think the majority of office and industrial installs would be suffering badly if this were not the case. Reaction score 4, Click to expand Reaction score 1, Cos I saw it done today!
Reaction score 3, Richard Burns said:. No because one circuit requires two wires at minimum and you only have three!! Marvo - Staff member. Reaction score 9, The neutrals went seperately to the fittings. Absolutely no logic to why it was done like that, it even used more cable than doing the job right.
Marvo said:. The only limits I know of regarding the number of single phase circuits allowed in any containment, including conduit, is the actual percentage of space that must be left to allow airflow without derating of the circuits being required. Darkwood Mod. Reaction score 10, Relating to an earlier discussion of using common multicore cable for multiple circuits ;; their isn't anything wrong with this as long as the insulation is rated to the highest voltage of all the circuits contained in the cable and that it is possible to locally isolate all circuits at one point, its slighty of track here from domestic but this is common in servo cables and machinery A lot of motors run one multicore cable that house both the motor feed and other control based wiring like thermal trip or force fed fan I think the op or his 'Mate' who has said this is getting confused with generated Eddie currents when not running all the phases of say a 3 phase load through the same conduit set or glanding points in a metal plate - which can give way to high heat generation and overheating of cables.
