2015年2月24日 · There are HDPE assemblies out there with conductors already installed in them - this can be labor saving, especially for directional boring applications, but they work great for instances where you are plowing the line in instead of trenching as well.

2021年2月15日 · We are pricing to move an overhead service to underground, I inform AHJ, local inspector for the area that we are considering directional boring due to the circumstances. He asks how we plan on putting the metallic direct burial tape or some type of warning tape 12" above the bore for future indication.

2015年11月4日 · I have a project that will use directional boring to install some conduits on the secondary side of a utility transformer. Basically the electrical conduits routed from the utility transformer, under a concrete courtyard, to the building main electrical room. I am not too familiar with this directional boring technique.

2014年3月23日 · Welcome Spring To All. Hello, I have to bore a hole under a 6' sidewalk. I am thinking about using a pressure washer to accomplish this task. Has anyone ever tried this before and if so did it work? I usually use a long drill bit for my smaller sidewalks (30"). Thanks,

2022年8月10日 · The voltage doesn't go infinite, just very high. A 400:5 CT is a transformer with 1 primary turn and 80 secondary turns.

2020年1月2日 · The problem is running NM where it's touching and there is no cooling air space. I believe (and I have no code reference for you) that as long as there is at least a 1/8" air gap between cables, you can run as many as you want through the same hole.

2024年8月5日 · The product is specifically for electrical conduit and is listed. It is about 60% of the cost of an e-loc coupling (my calculation of labor and material). I turned my directional boring subcontractor on to the product years ago and it is all they use now.

2024年3月5日 · Rationale for restricting perpendicular underside cable attachment is from what I see in 90% of homes that have an accessible basement level is people will use the cable as a hanger rod to hang cloths or other stuff from on the crossing cable.
