Run it awhile then feel the cord or connections if warm you need a heaver cable. Some times it not the cable gauge fault but the connections. now days i make my own cables with very beefy plugs and receptacles- the store bought ones just are not up to it.
I have had those molded on plug and receptacles melt down at half rated amps.
