Question about working voltage insulation

[Nuggie]

I think this language was put in to prevent cases where someone might wire a high, fixed voltage power supply across a single strip. Like a 100V power supply to a LED with 60V-rated insulation. But this is a huge exception and not at all how we assemble LED lights by using LED drivers that regulate their voltage to match what the LEDs want.

In addition, voltages in series...
Say you have 10 LEDs in series, with a forward voltage of 10V each, meaning the total forward voltage is 100V. If you apply 100V to this series and measure the voltage across any one LED, you'll still get 10V. No strip sees 100V, none of the connectors see 100V.

You really have to go out of your way with the wrong type of driver and a single LED to subject that strip to excessive voltage to risk breakdown of the insulator.

Shimbob you nailed it, only for fixed voltages and like you said we don’t run them like that

I’d max out at 150 volts if at all possible and less than 10 amps for a catch all
