Electrical Plan With Computation

While there are different methods doing an electrical design but there is only one thing that cannot be altered code requirements must be followed. Service entrance shall have sufficient ampacity to carry the building load they shall have the adequate mechanical strength and shall not be smaller than 8 0 mm 2 or 3 2 mm diameter except for installation to supply limited load of a single branch circuit such as small poly phase power controlled water heaters and the like. That one can read or prepare an electrical plan for the building.
