Yes but there might be difference in voltage drop for transistors then maximum
current is lower. For an electric motor sum of currents is the same so then
wind for a higher

There are some good reasons to use a 24 or 48 volt DC bus power system
for smaller systems.
The chance of electrocution is pretty low for a 48 volt DC system in a
dry environment.
Once you get above 50 volts or so things change.
24 volts is quite a practical voltage level for smaller systems.
