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?

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. 

@ditusa : my apologies after seeing your big Crown amp. How many wpc at 8/4/2 ohms? My Perreaux 2150B does 340/680/920@8/4/2 ohms. I will look and see what gauge power cord is on it. Also I was wondering if the MacIntosh 1000 watt mono amps use a 10 gauge or better cord?
