The weight of 250 mcm (thousand circular mils) copper per foot can be calculated using the formula: weight (lbs/ft) = (circular mils × 0.000001) × 0.321. For 250 mcm, this results in approximately 0.196 lbs per foot. Thus, 250 mcm copper wire weighs about 0.196 pounds for each foot of length.

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.
From the question it is hard to establish whether the service size is 350 amps or the service conductors are 350 MCM in parallel. If the service is 350 amps, the grounding conductor is #3 bare copper wire. Parallel 350 MCM conductors will allow for a 600 amp service. The grounding conductor for a 600 amp service is a #1 bare copper wire.
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.
