Why do you have to use a separated conductor for grounding and for neutral? ... If the ground and neutral were the same conductor, the cutting only the neutral wire (for example by accident) would cause the grounded metal case of the equipment to be on mains potential just because there is only live connected to equipment...

The electrician noted that an overload problem would occur, not with the phase conductors but with the neutral conductor. The phase conductors would be loaded to approximately 60% of their ampacity (B phase as worst case) while the neutral would be overloaded to 131% of its ampacity.

neutral conductor, amp service, copper line: Just so you know you can disregard the power of the A/C units because they never run simultaneously with the heat which is a higher load. But those are some serious heaters which must give you a nasty electric bill. ... Expert: Ivan Ramirez - 1/13/2008; Question; My power co.

amp service, neutral conductor, copper line: First of all it is not quite as simple as you describe it. You cannot have a separate 200 and 125 amp service at the same house. You would have to eliminate the old 200 amp service, install a 325 amp service, and from that install a 125 amp subpanel. ... About Ivan Ramirez; ... My power co.
