Pull a rope through first tied to the end of the old conductors, then use that to pull a couple passes of rags through to clean out the conduit. You should not have an underground junction box. Once the old conductors are pulled out, you can replace this with a continuous sweep of conduit. Upvote. # 4.
Your conduit first needs to be free of water or else the wet string will be harder (or impossible) to get through. You can suck out any water if you have a wet vac. If you don’t have a wet vac, you can blow the water out using a lawn power blower. 530 ft. is a long run but I think the shopvac technique should still work.
Lots of wire lube applied directly to the wires by the pusher as they go into the conduit. I'm sure your #4 is stranded wire, but get stranded for the #8 also. Taper the head of the pull by staggering the start of each wire and wrap it with electrical tape. Roll out the wires ahead of time to get the twists and kinks out.
Protect the HDMI connector by wrapping it in paper and taping around it, secure the pull string to the cable behind the connector. Attach a new pull string to be pulled along (so you have something to pull the next cable that needs to go in). Have someone feed the HDMI cable into the conduit at one end while another person slowly pulls the ...
There is a pull string already in the conduit. However, the length of the wire the installer left is not long enough. On one end, the string extends just 6 inches past the opening. 4 inches on the other end. I will find a way to splice another pull string to the existing pull string.
Take 3 or 4 strands from oppsisite sides of the wire, pull outward, cut off everything else. Then fold those in half so they fold towards each other. Those both will be placed through a loop on your rope or fish tape. Do this with each of the conductors.
It's likely the wire is getting stuck right at the end where the weatherhead attaches or just above the meter pan. Make sure the wire is straight when put in conduit. Sometimes you have to use a screwdriver to guide the wire past the fitting. Upvote. Electrical - AC & DC - Pulling 2AWG copper wire through conduit to weatherhead - I've managed ...
Having the conduit burried and pulling the wire is 100% easier and faster. Heres a tip: pull the rope through and put both ends in the same area your wire will be (exactly the same). Mark the rope at that length and pull it back out. Measure the rope and you'll have an exact length of wire needed.
For Southwire brand 12-2 NM-B cable, that diameter is 410 mils, according to their website. That gives an area of 0.132 sq. in. Look in the appropriate table for the type of conduit you're using, e.g. Table 4 for EMT. Read across the 3/4" trade size row. In the 1 wire column, it shows that 0.283 sq. in. is available (at 53% fill), so 1 cable is OK.
Wires are THHN, longest pull between pull points is 70' +/-, ells are long radius, new pvc conduit buried and above ground. One end of the long pull is in a 10" at grade pull box with the 45 bend and the other is a condule, all other bends in the remaining 40 feet are through condulets.
