Some reels have 2 ratings, and some newer and larger models have a thermal cutout. In my experience most that are in common use have neither. The ’wound up’ safe rating for say a 25m reel with decent cable about 1.25mm2 cores is typically around 700 watts, so not a lot.They normally have 2 ratings printed on the spool. One for wound, one for unwound.
…but some people tend to ignore this and then wonder why the cable is very warm!
And when they catch fire, they really go up as the cable insulation plus drum is plastic.
