In the CEC only 1/0 and larger conductors can be run in parallel.

What size ground wire is required for 80 amp service?
Ground is sized based on the size of the feeder wire and not the amps of the service! However, for a 600 amp service 1500MCM copper wire is one option (NEC 310.16) ;therefor, ground wire is 3/O copper (NEC 250.66) or another option is a two sets of 350 MCM copper wire then a #2 copper (since the biggest feeder wire is 350MCM).
How much does 500 mcm copper wire weigh per foot?
About 1.5 lb per linear foot. A Circular Mil is the area of a circle with a diameter of 1/1000 of an inch. The first "M" actually stands for 1000, and "MCM" is interchangeable with "kCM." 500 MCM has an cross-sectional area of 253.4 sq mm (2.534 sqcm, a density of 8.96 g/cc. 1 foot is 30 cm. 2.534*8.96*30 = 692 g = 1.52 lb. Of course if you're using 500MCM cable you're probably installing it in a 3-phase system, with possibly a full-size neutral, so for total runs, you may have a 3-4 multiplier for a total weight of a single set run.
What size ground wire for 350mcm?
1/0 copper
What is the cable size required for a 400 amp and 350 amp load?
350mcm
Can you bend 90 degrees in 10 inch box 350mcm?
If you bend 350MCM at a tight 90 degree you will break the internal conductor. You should be able to feel the cable and feel if you are forcing it. It will need room to curve (make a radius) in order to make a transition from vertical to say horizontal. Unfortunately, much of the older cable will be brittle and you may snap the insulation.
