A 3/0 copper conductor with an insulation rating of 75 or 90 degrees C is rated at 200 and 210 amps respectively.
A 3/0 copper conductor will limit the voltage drop to 2% or less when supplying 200 amps for 80 feet on a 240 volt system.
Windows that can be opened.
Three feet clearance is needed in front of electrical service equipment.
CEC - any window that has the capacity to be opened.The exterior electrical service wires should be at least 3 feet away from any part of any window that is able to be opened.

3.33 FEET = 1 METER A more accurate answer is 1 metre = 3.28 feet.
It has to be at least eighty feet away Not it has to be fifteen
There is no specific distance specified in the code book. The meter stack has to be on the outside of the building and some times this means bringing it through the eave end of the roof line. The connection point has to be 15 feet high as a minimum. The utility meter has to be at head height on the outside wall for the meter reader to see and read it. On the lower end of the meter stack is the electrical panel. As you can see the distances will change in every circumstance depending on where the electrical panel is placed. The electrical panel can not be placed any further in the building from the outside wall than ten feet.
In the CEC (Canadian Electrical Code) the code states that from the outside meter base to the first over current device that, the run can be no longer than 20 feet.
No, nor under a stairwell. The electrical code stipulates that there has to be 3 feet or 1 metre in front of an electrical panel for clearance for easy access. The panel being in the closet does not fit this criteria.
In front of any electrical equipment, there has to be a free space of 1 metre or 3 feet. This is so that the equipment can be worked on without any obstructions being in the way. A clean work space is a safe work space.

Meter's are bigger, 1 meter = 3.2808399 feet.
Depends on the size of the sub-panel in that garage. If you are installing a 60 amp sub-panel 400 feet away from the main service panel then use AWG # 4.
