It depends on the type of Power systems Whether AC ( single or multi phases) or DC ( 2 or 3 wire ) .....ETc
A capacitor is a capacitor, no matter what circuits you use it in. There is no difference between one used in AC and one in DC, except perhaps the size that is appropriate.
In a 48V DC system you ground the positive to 0V so the live wire will be -48V.
how to know dc cable sizes
The main cause for a meter to read negative voltage across a DC motor is a loose ground wire. The ground wire can be loose or may need to be cleaned.
The simplest way is to buy a DC power supply that plugs into 120 VAC as its power source and the output is DC at 230 VDC either fixed or variable. Make sure it can deliver the current your device requires and that you use the proper size wire for the DC connection based on the amperage.
for DC load and if its copper wire the cross section of the conductor wire is generally calculated as 1/4 th of the current rating . Eg for a DC load of 16 amp the copper conductor with 4 mm square is selected.
Brown
For a 12V DC system with 200A current flowing through an 8 ft length, a wire gauge of at least 2/0 (00 gauge) is recommended to ensure minimal voltage drop and for safety reasons due to the high current involved. Be sure to use proper insulation and keep in mind the wire material as well.
of all of dem 3 phase 3 wire is most economical as it uses less conductor dan in 4 wire system, 3 phase 3 wire is used in transmission and 4 wire in distribution as it has 3 live and one neutral wire. 3 phase needs lesser conductor size than 2 phase 4 wire for the same power. 3 wire dc feeder is more economical than 2 wire dc feeder for the same power. that was all i cud get..... hope u find it a lil helpful.
Typically black. DC +ve wire color typically red or brown.
The white stripe on a DC wire typically indicates a negative or ground connection. It helps distinguish the wire's polarity or function in a circuit to prevent incorrect connections.
that depends on,motor size, number of coils, company,and wire gauge. you can make a simple dc motor with just 10 winding or less. it would be very low on torque and speed though.

The voltage applied and the resistance across it.
