in 3-phase yes

in single phase they may be used for things like 3-way switches in place of duplicate black wires and thus would not always be hot

Which is the hot wire if there are both black and red wires?

The hot wire could be either the black or red wire, as both are commonly used for hot wires in electrical wiring. It's important to use a voltage tester to determine which is carrying the current before working on the wires.

How do you hook up ele plug in wires coming in to house the plug has white black and ground wires and the wire from the house has white black red and ground hooked to a 30amp fuse?

You will have to check to make sure. Normally, with 4 wires, the black and red are both power for 220. White for neutral and bare for ground. If you are only using one leg of it, you would use the black, white, bare ones and cap the red one. Someone may have used the 4 strand because they had it or 220 was planned but not done or both the red and black are hot. You should be able to tell in the panel. Do the red and black both connect to separate breakers or to one or is the red not connected?

What colour insulation is used for active conductors?

Active conductors are typically insulated with colored sheaths in accordance with industry standards. In most cases, active conductors are insulated with colors such as red, brown, or black to indicate the live or phase conductors. This color coding helps to easily identify and differentiate active conductors from neutral or ground wires in electrical systems.
