The bare conductor is about 1.05 lb per foot. Insulated wire weight varies by type of insulation.
The weight of 350 MCM (thousand circular mils) per foot depends on the material it is made of. For example, copper 350 MCM wire weighs approximately 2.6 pounds per foot, while aluminum 350 MCM wire weighs around 1.6 pounds per foot.
The weight of 750 MCM (thousand circular mils) wire will depend on the material it is made of, such as copper or aluminum. Copper 750 MCM wire weighs approximately 1.74 pounds per foot, while aluminum 750 MCM wire weighs around 1.09 pounds per foot.
2.2 lbs per ft
There is no defined AWG for 350 MCM. The American Wire Gauge stops at 0000 (4/0), and 350 MCM is bigger than this. An approximate conversion would be 6/0, if there were such a thing. Extrapolating out from 4/0, 6/0 is 334.8 MCM, and 7/0 is 422.2 MCM. These wire sizes don't exist of course, and don't exactly match 350 MCM anyway.
The diameter of an insulated 750 MCM copper wire is 1.25 inches. The insulated 750 MCM copper wiring has 61 strands and has a weight of 2.7 pounds per foot.
500mcm 37 strand copper wire = 1.544lbs/ft.
250 MCM copper wire weighs approximately 0.311 pounds per foot.
The required size of the service grounding conductor for a 350 amp parallel service will depend on the specific installation requirements and local codes. It is recommended to consult with a licensed electrician or engineer to determine the proper size based on factors such as the type of wiring used, the distance between the service entrance and the transformer, and the local ground conditions.
400 MCM (thousand circular mils) copper wire weighs approximately 1.51 pounds per foot.
The weight of 3/0 copper wire is approximately 559.5 pounds per 1000 feet. So, the weight of 3/0 copper wire per foot would be approximately 0.5595 pounds.
A 1000 feet of 300 MCM wire weighs 1021 pounds. It is easy to calculate from there.
