12 Gauge Wire Rating - Ask ohm. Energy dissipated in a resistor (a cord is a resistor, inside the real global) is r*i2. Voltage doesn't come into play for strength dissipated in a resistor, though you could calculate the voltage drop as v=ir.

Amperage doesn't care approximately voltage, amperage simply cares about how big the cord is. 30 amps is 30 amps, doesn't count if it's 12 volts, 120 volts, or 600 volts, you still want 10 gauge cord for 30 amps.

I'm curious why you assert that? He has approximately nearly 100ft of led light strips. Ime led strips are about .12 a/feet. So he is looking at about 12a of call for. I'd additionally hazard a bet that at \$120 for the complete task he were given a cheap "30a" electricity deliver that, if it's anything just like the cheap strength elements i've gotten online, shouldn't be trusted beyond 15-20a.

What is the modern-day draw of each strip? This needs to be recognised earlier than anything else; the psu being 30a approach it could supply up to 30a however the actual draw is dependant on what is related to it (i.E. I will positioned a unmarried led on my 60a supply however it's going to still best draw zero.25a).

Electricity strains are an thrilling case in that they're generally uninsulated (in phrases of a coating on the outside) - they depend on the gap from different items (and other lines) to save you arcing. In case you were actually handling 30 amps, you'll need at the least 10 gauge wire. In case you're only coping with four amp circuits, you're first-class the usage of 16 gauge twine. Simply buy a reasonably-priced extension twine and cut the ends off, if you want to stick with nec for interior wiring, your most inexpensive choice is 14-2 romex. 10 awg is accurate on this example however as an electrician always do not forget with lighting fixtures it's miles taken into consideration a steady draw so continually estimate it to be one hundred twenty five of what you determine and also you shouldn't smoke anything too badly lol.
