Well as for 200A cu.svc being cheaper than parrallel 4/0 400A svc I'll have to say no. Actually the cost was about equal.
Actually AL is a better deal because with it I (cousin) get a larger service. And the power company supplies the meter-can so there is no additional cost there.
So if he ever wants to open a small amusement park in his backyard then he should have no problems. HEHEHE
We (power company) had a guy that his electrician had installed a 200A 4/0 AL underground svc that ran about 200'-225'. Voltage at the trans was around 120 or 122. By the time it got to his house and under full load he had less than 110V. They somehow got it approved for him to install 4/0 cu. and we actually hooked it up. After I connected it and checked voltage I was getting 120V at the meter without load. I hope that solved his problem. As far as I know he hasn't called back to complain about low voltage.
