Installed Transfer Switch, Pigtailed the wires to the Panel

While installing the transfer switch I decided to pigtail the extra length of wires instead of cutting them to length incase I decided to power a different circuit later. Is this a code violation? A possible fire hazard? At first I didn't think it was a big deal because I saw a white wire in the panel that was placed that way.

Should I just remove the extra slack and get rid of the coiled wires? Its been this way for a year without a problem. So i'm not sure why its bothering me now. Thanks for your help .

Welcome to the forums! No, you can leave the excess wiring in the panel. Ensure it is not apt to be chafed or a panel screw driven to pinch it. Otherwise, no code violation. You have just run out of worries in your life, hence the wires bothering you. It happens. Rest easy!

I read somewhere that coiling the wires can cause an increase in resistance and hence a slight increase in the wire temp. I guess it will be an insignificant amount?

Coiling the wire might cause a higher impedance (essentially AC resistance) and under certain circumstances it could cause excessive heating. Electrical codes require that all work be done in a "neat and workmanlike manner" and while workmanlike is not further defined, in my opinion the excess wire simply coiled up is NOT a workmanlike manner. If it were mine I would go back and remove the excess coiled wire.

Provided that the coiled up wire isn't crowding the panel box, I would leave it there for now.

I am guessing that added heating from the coiled up wire would be negligible.
