# Number of Conduits run and number of circuits

Discuss Number of Conduits run and number of circuits in the Electrical Wiring, Theories and Regulations area at ElectriciansForums.net

Welcome to ElectriciansForums.net - The American Electrical Advice Forum

I am in estimation and often estimate conduits run in the drawings. My clarity about number of conduits run is not good.
I want to know that in multiple circuits zone, how we calculate number of conduits run to the panel.
For example. If i run conduits from Ckt A-1 to ckt A-2, i need Two number of conduits. Then from Ckt A-2 to ckt A-3 i need Three runs of conduit and when i run from ckt A-3 to panel altogether, conduits will be 4. But i really cant figure it out for more than 4 circuits run to panel. And what is the relation between number of conduits and multiple circuits.

Yassima it you are pulling singles then what you have to know how many wires do you need from a1-a2 and etc. then you can size your conduit accordingly if you are pulling cables you have to double the conduit size

Hello @yazirnaeem is this applicable to Canadian installations, if so we have a Canadian forum I can move this to.

@westward10 it is general query. I dont think so its applicable to any country specific standards.

@Megawatt i am running singles but would like to join different circuits at box and want to take it together to the panel. Size of conduit is ok for me, but i am confused due to number of conduit runs.

Are the singles you are pulling for controls, motors, analog circuits or all of the above. I going to guess that you have some Cat-5 cable also

Go to NEC then go to informational annex C table C8 chapter 9 you need to know how many wires you need before you even start worrying about the conduit. Don’t look at the big pitcher just take it 1 conduit at a time and what size you will need

i am just pulling power cables for lighting circuit. But i think nec info is good. i will look into it.

a general rule is that the cables should not take up too much of the space in the conduit to allow for heat dissipation. this may help:

Taxi since you are just estimating you must have a drawing to go by, does it have what size pipe, what size wire, what devices you are estimating and the part that confuses me that your pipe is your biggest concern. I used to be a project manager/ estimated. Do you have pitchers of just the part with the conduits. Nobody is going to be able to help you without more information.

Is that another American electrical term?...or are we talking baseball or big jugs.
By the way, 'Big Jugs' in our english come in pairs.

In your post it say pitcher rather than picture, is this an autocorrect issue or a UK/US thing?

Yasi how many wires do you need for A1 to A2 which sounds like a cool if it is a cool just 2 wires

think the problem here is american auto spell check, OP says pictures and spell check, knowing the American obsession with baseball ( we call it rounders) changes it to pitchers. hope this clarifies the problem. apologies to megawatt for taking the pi\$\$ out of his national sport. .

If Canadian wiring regs are similar/same as US, grab yourself a copy of Uglys, it's Thier version of our OSG and it will have tray fill capacities in there.

Lister I actually have an ugly book and it comes in handy. I use it more than the code book, you can find stuff fast

24 hours late.forgotto hit the "post" tit
some areas of the UK do. basically. all the competitors drive their pigeons to a distant location, release them, and the first ones home win. . almost as stupid a hobby as fishing.

That's true but it has opened discussion and shared education about different country ways of working.

I think it may be prudent if, for the major countries we identify (US, AUS, CAN etc) what that countries regs are and, if digital copy exists; link to it in a sticky (or where to purchase hard copy), that would serve to help users from those countries and give those on here that want to offer help/advice a reference point to check thier advice against.
