2-2-2-4 MHF in conduit

[dave89iroc]

what size conduit should I run to run the MHF in it? I am likely going to run conduit the entire distance from the house to garage(~40 underground)

2" minimum IMHO. Even then it will be hard to pull around any kind of bends.

Same and use sweeps and grease to get it through.

It will go 1 1/2 that distance and 4 turns dry, 2 inch will be easy.

I did same run...... 2" pipe, 2-2-2-4 mhf. Multiple 45's and 2 90's.... Pull was not hard at all.... just have someone feeding it in straight...

I'm using 3" so I really should have no problem. Run is about 70' with a few 45,s and two 90's. I'm aware of using grease but I have to ask......what are sweeps?

 

[wyliesdiesels]

Sweeping 90s as opposed to short 90s

I just did that and my biggest mistake was to not stagger the cables in the beginning so it was hard to get them thru the elbows.
I used 2" pipes and lube and my run was 100' but I had a pull in the center so it was 2 x50'.
The first 50' were hard but the second 50' in the other direction were easier even it had more bends because I staggered the cables.

thanks, I am only going to need 3 90s, and maybe 1 45

Also, pull a stiff rope - like a good nylon type - though the pipe for a pull string. Also, watch your joints because it can hang up on the edges of the next pipe after a turn. You can use a sanding drum or a file to take the sharp edge off the pipe ends to let it ease on by.

2" is fine. I used 2.5" pipe.
Lots of lube from electrical dept and a strong rope.
Tie a mason string to a plastic bag. Put a vacuum on one end of the pipe and the plastic bag on the other. That is how to get the string through the pipe fast!

I used 2" for 125' with two sweep 90's. I had no problem working alone. I did use lube.

I cheated and pulled the wire through all the pipe and fittings separately on the ground and then fed it into the trench from one end to the other gluing the fittings as I went.

2" tube, two 90s and a 45 plus a gradual curve over 90 feet or so. The grocery bag and mason line trick is stupid fast--as soon as the vacuum kicks on it's there. Just be careful pulling your muletape with the mason line--if it rubs too hard it'll start to cut through the conduit.

I used plenty of lube, staggered the conductors, and had my wife feed it in from one end while I pulled the other. Took us about 10 minutes.

^ ^ ^ Good advice above.

+1 for using 2" conduit.

Minimum of 2",do yourself a favor and buy a pulling sock.

I cheated too!
