Re: Electrical Confusion


I believe weíre going to be reusing some older style dusk to dawn lights which we had on the driveway before or purchasing some cheaper LEDís. We used to feed the power from the bottom by the road but that power is cut now so we have to go from the top. There is only going to be 4 lights. Not really interested in putting a transformer in and all that. Just want to run cable underground to power the lights from top to bottom of the driveway.

The "ring" circuit fascinates me... I'd consider using it on work bench outlets and kitchen counter outlets to improve performance.

A ring circuit on one's plumbing might actually yield more noticeable improvements in steady supply rates and temps....
Uhhhh....Watts is watts. 240 at 1 amp or 120 at 2 amps is the same cost.

More losses at 120V. But we're probably talking pennies.

Re: Electrical Confusion


The Voltage 'drop' is wasted heat emitted by the 400' of supply wire...

30 years of night lighting = well over(allowing for dusk and twilight effects at middle latitudes) ~100,000 hours of operation, ONE penny/hour saves 1000.00$, enough $ to totally replace the system.....

Or you could use 14 gauge wire with 240 VAC powersupply to save ?40-80.00$ material up front?

What should I replace the system with? Keep in mind we donít want to throw too much cashola into this project. More of an extra want than a need. Thanks!

Re: Electrical Confusion


The old school bulbs are definitely economically obsolete, can you use new LEDs in old hardware?

For me the "big" thing would be the labor of trenching in the 400'+ of wiring... but once in, it should work with most types of LV systems, You could install the legacy/free tech, and update it with LEDs as they fail...even run old and new power-supplies if needed during the crossover.

A little more power for a motion activated wifi camera(s)? At property line, with hardline buried with the UF wire?
