It’s these electrical loads and those like ‘em that ought to be singled out for special attention when rating an electrical circuit wiring in a residence. The AG does this every chance he gets. I know, for sure, that he could be in a minority of one. He’s unphased (a little electrical pun, there).
3) One electrical circuit wiring at a time shall be distinguished
a) as dedicated to home light electrical loads, which electrical loads shall be connected only to that electrical circuit wiring
b) as dedicated to non-light electrical loads, which electrical loads shall be connected only to that electrical circuit wiring and
c) a home light electrical circuit wiring and a non-light electrical circuit wiring shall not be interconnected, including as to grounded neutrals
Comment: Wrote an electrical engineer client, “I’m very glad you made it clear that home light and non-light electrical circuit wiring shall never mix. Not just for safety, but changing to LED home light [in] the future will be much easier.”
4) Computer equipment and entertainment centers shall be supplied by individual electrical circuitry wiring at not greater than
a) 2 separately boxed hard drives and a printer or
b) 2 printers and boxed hard drive(s) per electrical circuit wiring and
c) a sized Uninterrupted Power Supply (a/k/a UPS) with surge protection shall be urged
Comment: The AG and the Missus convey herewith their dedication to applying UPS units of quality between their pricey tools, their precious work, and the irregular supply of electricity from their local electric utility.
A while back before we figured it out, they lost 3 motherboards and 2 hard-drives to power dips and spikes, many so fast individually that there was no dimming of home light or loss of digital readout time. Now, they can sense these extremely brief power blips listening to their UPSes click on and off, sometimes in bursts.
