No, there are different occasions when the red of a three wire cable gets used as a hot wire. There also times when the white wire gets used as a hot but has to be re identified as a hot with marking tape. When wiring baseboard heaters the cable used is red and black with no white wire in the set.

The white is neutral. The house does have a neutral wire even though it may be black. One of those black wires is the neutral and the other is the hot wire.

If it is in a house generally black wires are hot and white wires are neutral (common). The neutral and ground wires are tied together in the main panel.

If you get no reading it could be classified as common. This is the normal wiring practice. This is a basic assumption without having 1st hand knowledge of the wiring system If in doubt contact a qualified electrician
