Correct wire size L 14/30
« on: October 25, 2023, 08:28:19 AM »

Title says it all. Running an amp rack with two PL 380 and two Crown 12000 HD. Thats all it will ever be used for. I have a 100 ft of 10g. Do I need bigger?

Are you intending to keep the length 100 ft?  If so, the potential load from those amplifiers is sufficient that I'd up-size to at least #8 and run the ITechs @240V.

I was hoping to do one 75 and one 25 with the wire I have. Most stages/ show we do that would do both sides. But if you think 8 would be better I'm off to the market

Everyone I know just uses 10ga for 30A circuits under 100'.

8AWG is what you need for a 30A circuit with 3 current-carrying conductors.  10AWG is acceptable for 2 current-carrying conductors.  If you connect that L14-30 to 2 legs of a 3-phase supply, the neutral is considered current-carrying, and even if you're fed from a split-phase supply, supplying nonlinear loads (of which switching power supplies are an example) also causes the neutral to be considered a current-carrying conductor.  Which is a long way of saying that 8AWG would be the appropriate wire size for this application.

Yes, #8 is correct, SOOW.  You will need lots of pennies in your pocket the stuff is around $4.00 a foot where I live in Cleveland OH.

Look on Amazon at cords that are already assembled. I bought a 100' 6-4 with 50A C type connectors for less than $400.00, which with connectors was a killer price at the time. It is sold by Southwire. I have a couple different adapters for different receptacles to cover different venues. This way I am always covered. Or at least so far so good.

Is the SEOW a typo?  That is not a bargain if it is not SOOW. SOOW is just a bit about the $4 a foot range.

It is SEOOW. At that time I bought it was $4.50 per foot plus buying the connectors and having to install. To buy pre-assembled for $379.00 was a better deal for me. Actually it may have been a little more per foot when I ask for a quote, it has been several months. I just remember for me to buy the 100' of cable without connectors was more than buying a cord completed.

The issue is SE is less than 1/2 the price of SO.  To me it feels the same as SJ even though some of the properties are superior to SO. 

Plastic cable just doesn’t belong on a stage.  It doesn’t sit flat and sure doesn’t roll correctly.
