Anything with electrical current running through it will dissipate some
degree of heat. Rheostats can run hot, depending on their setting and how
much power they are controlling. Fuses can get uncomfortably warm to the
touch. Wires and connectors should never go beyond luke warm. These are just
unscientific guidelines.
