Quoted from zacaj:Using a smaller gauge wire would definitely be bad. A bit bigger shouldn't be an issue.
You are backwards. The lower the gauge, the thicker the wire. I think you meant using a smaller diameter wire would be bad, a bit bigger shouldn't be an issue. Also, for what it's worth you cannot tell the gauge of the wire by just looking at it. Different wires have different thicknesses of the insulation. But yeah, in general, thicker wire would not be your culprit.
