Leviton Comment: We combined these two articles
here because they both relate to the same area.
Change Summary
• Back in the 1920 NEC the voltage threshold increased
from 550 volts to 600 volts. Then in 2017 the NEC
included content addressing thresholds to 1000 volts.
Today electrical technology is expanding quickly with
technologies like photovoltaics and others. The NEC is
keeping up and this article is an example.
Article 245 Overcurrent Protection for Systems Rated
Over 1000 Volts ac, 1500 Volts dc.
