What else can I help you with?
What is the polarity of wires when you have a black and a white wire on a 12 volt radar?
In a DC circuit, the black wire is typically the negative (-) wire and the white wire is the positive (+) wire. To ensure proper connection, always check the specific wiring instructions for the radar system you are using.
What are the differences between DC wire and AC wire, and how do these differences impact their performance in electrical systems?
DC wire and AC wire differ in their ability to carry direct current (DC) and alternating current (AC) respectively. DC wire is designed to carry a constant flow of current in one direction, while AC wire is able to handle the rapid changes in current direction that occur in an AC system. These differences impact their performance in electrical systems as DC wire is more efficient for transmitting power over long distances with minimal loss, while AC wire is better suited for powering devices that require frequent changes in current direction, such as household appliances.
Is the red wire hot or common?
If wired correctly the red wire will be hot, but any wire can be hot regardless of colour if done incorrectly.
On a DC wire what is the white stripe?
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.
Can a 220 volt dryer be gfci connected using a 3 wire system?
Yes, a 220-volt dryer can be connected using a GFCI in a 3-wire system, but it is not the most common or ideal setup. Traditionally, dryers are connected with a 4-wire system for safety, which includes a separate ground wire. If using a 3-wire system, ensure that it meets local electrical codes and that the GFCI is rated appropriately for the load. Always consult a qualified electrician for safe installation practices.
How do you get -48v DC?
In a 48V DC system you ground the positive to 0V so the live wire will be -48V.
Explain the comparison between dc 2 wire system and ac single phase 2 wire system and ac 3 phase 3 wire system and ac 3 phase 4 wire system?
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.

How do you wire -48v dc power and ground to earth?
always think of any supply system so : RED = MOST POSITIVE BLACK = MOST NEGATIVE in a telecom system the -48V supply is refferenced to ground and earth, so the supply wire is NEGATIVE, this means a DC supply most positive signal the RED wire, go to EARTH = ZERO, the BLACK wire is the MOST negative, so in this case it is -48V
Is the red wire hot or common?
If wired correctly the red wire will be hot, but any wire can be hot regardless of colour if done incorrectly.
What is the common wire color?
green <<>> In North America the common (neutral) conductor is white. The ground wire is green or bare depending on its location in the system.
What is the proper way to connect the black wire on a thermostat?
The proper way to connect the black wire on a thermostat is to attach it to the terminal labeled "C" or "Common" on the thermostat. This wire provides power to the thermostat and is typically connected to the common wire from the HVAC system.
In dc electric Which wire is positive?
Brown
What is the fast stat common maker used for?
The fast stat common maker is used to simplify the installation of a thermostat by converting a 4-wire system into a 5-wire system, allowing for compatibility with a wider range of heating and cooling systems.
On a DC wire what is the white stripe?
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.
A DC ground wire coming from a power supply output is typically what color?
Typically black. DC +ve wire color typically red or brown.
