# Basic Question about Power Cables

Hi,

So I was thinking of changing out the stock power cable on my amp and one cable I was looking at said not to run more than 15amps through the cable. I'm not entirely sure how to approach that. How do I find from the specifications of my amp whether or not it violates that?

Look at the connection of the power cord to the amp... if it's a 15A IEC inlet, it will appear to look like a barn, or house... a 20A IEC will be flatly rectangular... the two corners won't be cut off as with the 15A. 08-17-2008 4:46pmLook where the IEC is on the amp and it will tell you its AC power consumption in watts. To put that number into amps do this easy math: Power in watts divided by 120 = power in amps. Also like Jim said If you have a 15A IEC you'll have vetrical blades whereas a 20A IEC has horizontal blades. Most have 15A. ET 08-17-2008 7:06pmOn the back of your amp it should state the voltage and current draw - it should say something like "120 V 15 A". V = Volts, A = Amps.It may, alternatively, have something like "120 V, 600 Watts". Since Watts = Volts * Amps, divide the Watts by the Volts and you get the Amps - 600/120 = 5 amps...-RW- 08-17-2008 11:08pmThe above all assumes you're in the US with 120V supply. If you're elsewhere with a different mains voltage, make sure you use that figure for any calculations.That said, your amp is unlikely to draw anywhere near 15amp; that would be 1800 Watts, assuming a 120V mains voltage. 08-17-2008 11:25pmAh ok, thanks a lot ET and RW 08-17-2008 11:26pmAnd yes, I do live in the U.S. Thanks for the clarification as well Carl 08-24-2008 6:16pmHi Guys,please visit www.lessloss.com and get the cords - I have just done it and they made my Valhalla sound sick!!!I was luck because the factory is only 50 miles from my house so actually the owner Louis Mortek came round in person and wehad a great session yesterday - I can send pics if you want =I was also able to try the Firewall which is a unit that get rid of the crap from the wall outlet/sustations/power sataions etc it just took the music to a different level and I nearly cried when he packed it up because it will not be released till next month at the show in Colorado -Hope this helpPaul
