Section 8 of the CE Code is absolutely critical, as the accurate load calculations constitute the basis for selection of the appropriate conductors’ sizes in services, feeders and branch circuits
In the world of electrical power, copper clad aluminum is the third of only three industrial metals referenced by the NEC as acceptable for use as the core-metal conductor in residential branch circuit conductor applications.
Today we have daily PV inspections, and some are supply-side connected. Article 705.12(A) Point of Connection (Supply-Side) points the reader to 230.82(6) for the allowance to connect to the supply side of the service disconnecting means.

Even though each step brings us through exciting adventures and places us closer to our goals, I approach 2017 with some apprehension, maybe more uncertainty.
Hydrokinetic turbine generation process uses flowing water in the form of ocean tidal energy, river in-stream energy, or ocean current energy to generate electricity.
Working with electrical systems has inherent risks, and working with Renewal Energy (RE) systems is no exception. This article offers a look into the installer’s world of required electrical safety guidelines and procedures.
