Do I need 10 gauge power cord if I have 10 gauge from panel?


I just installed some dedicated circuits with 10 gauge electrical wire. But now I have to consider replacing my amp power cords because they are 14 gauge or higher.

Is this really necessary and any recommendations on quality 10 gauge power cords that I should buy?

@pennpencil Exactly!  If you hear a sound quality improvement by upgrading power cables then proceed as your finances allow. You don’t need to hire an EE to tell you what you hear.  

14 awg is never big enough for an amp.   I have seen 10 awg power cords make huge difference in 5 wpc amps. 

The logic of @johnnycamp5 above is exactly why so many people have undersized power cords for their amps.  But I'm ok with that.  I've bought 2 excellent amps used and cheap that I concluded were sold because the owners had undersized power cords on them.

It’s just physics.

If a 4A fuse doesn’t blow during heavy use your likely not exceeding the 15A (14 gauge) power cords current capacity …

It may or may not cause you to hear a difference, perhaps at how much voltage sag a particular setup creates, but that’s personal/subjective to each person …

@pennpencil good point

FWIW I built my own power cables using Furutech bulk cable and connectors. You can buy what awg you want as well as shielding. I made mine custom length to each component. I bought cable covering from Amazon and some shrink tubing for the ends. It was fun project. Cost was around $170 per cable. You can buy less expensive connectors if you wish. 

I should have added that every circuit in my home is 20 amp. It was built that way and not something I did as we bought it from the original owners.
