IMHO you do not have a clue.

Sorry... I'm done and will not bother you anymore in any of your multi threads...

Please be very careful in what you choose to do. You are playing a very serious game of "You Bet Your Life".

Please stay off my threads, sir. I'm a high school english teacher trying to upgrade my brewery, not an electrician.

HERE'S where I got my information on how many wires are allowable in 3/4" conduit.

If I handed you a copy of Dante's Inferno and watched you teach it, I'm sure it'd be equally confusing. But in my line of work, we welcome questions and don't belittle others.

Again, please stay off my threads. The last one got deleted because you can't act like a decent human being.

For most conduit, that is acceptable. Properly installed metal conduit is an approved bonding method between enclosures. You did not mention what conduit you are using...

You should pull once (plan ahead). Adding a wire can be tough. If you pull them all out, attach the ground and pull them back in, you will be much happier and spend much less time and curses

EDIT...Soap/Lube is for big wire...it should not apply to breweries...JMO

It's metal conduit (EMT) and it does have 3 bends. Here are some pics:

Control panel


Conduit run to receptacles

It's EMT. I think I mentioned it in the first post.

Can you give me a primer on how you would I pull all 10 wires at one time? Do you just tie them in a bundle?

I'm willing to redo it if that's the best plan.

As long as the fittings are wrench tight it should be sufficiently grounded. How are the boxes connected together?

10 would be the absolute max, and I would lube them to reduce friction and scraping. It's easiest to hook one wire to the pull string I'd fish tape and tape the rest(tightly) to the hooked wire. As for the ground its more than to code to use emt as a ground as long as the couplings nd connectors are tight. I'm an electrician with info not judgement(pj) so feel free to PM me with any ?s! I always like a challenge!

I'm sorry. I guess I missed that.

You will need a pull wire/tape/rope of some sort in the conduit. If you plan to re-pull, attach your pull wire to the ones you pull out and pull it in as you pull the wires out. This all works best with a person on each end...

Once you have a solid pull wire/tape, attach the bundle of wire you want to pull in in as compact a package as you can manage. Tightly wrapped electrical tape 6-8 inches down the bundle is usually all it takes with maybe one wire looped through the pull wire/tape. Make the connection as compact as possible! Staggering wires can help keep the end small and get you around bends.

Lube does help if you have lots of bends or too small conduit. Murphy's Oil is what the old timers used if you have that in your cupboard. The most important part is keeping the wires in a nice bundle while feeding in. A big spaghetti mess takes up much more space...

Work smart....best wishes

I used box spacers.

Just use a ground screw or a grounding pig tail in Your handy boxes to insure a good bond, unless there is metal on metal between the boxes. The ground screws are reasonably cheap at home chepo.

All those 90's are making it a tough pull.
