It would depend on what you are using. A direct current motor has a negative and positive terminals. If connected with the wrong polarity - red on black, black on red it will go into reverse possibly causing damage. Car batteries are used as dc. A lot of small appliances may be dc. Best to check the item you are using and connect the right polarity whether it's AC or DC.

Why dc series motors cannot be used in home?
DC series motors run on DC power. Homes have AC power, not DC power. You could use DC motors in homes if you have a power supply or use a battery, but it is usually more cost effective to use an AC motor.
