120v versus 125v
(OP)
What is the differance between having 125v on the drawing, and 120v on the product?

In the drawing, you need to consider the expected worst case. In this case, you expect 125 V. On the product, you put a buffer, and say it's 120 V max, where the nominal voltage is 110 or 115 V.
Citing another example, as per rules, any pressurized container should be capable of withstanding upto 7 times the nominal(normal operating) pressure. Type manufacturers design it for 10 times the nominal pressure!
