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?

@jumia The power cord you need to your amp is by the breaker on the amp, not the panel.

Jumia, should have been more clear.

The gauge of wiring you _need_ to your amps is dependent on the fuse or breaker value on the amp itself.  14 gauge is enough for up to 15 Amps, 12 gauge for 20.   You _could_ get thicker wiring but not needed.  I personally like shielded cables over thick cables for the extra EMI/RFI protection.  Now that our homes are filled with wireless devices and Ethernet and USB cables I feel this is more important to me.

The biggest improvement is in reducing resistance per foot.  If you ran 30' of 10 gauge it's still better than 30' of 12 gauge.

Just make sure your breakers are right sized for the end use.  Meaning 15 or 20 Amps.
