What is the trade name for this cable romex?

Romex is the trade name for non-metallic sheathed cable manufactured by Southwire Company, LLC.


Is it permissible to run Romex cable in conduit?

Yes, it is generally not permissible to run Romex cable in conduit because Romex is already insulated and designed for use without additional protection. Running Romex in conduit can lead to overheating and potential fire hazards.


Why can't you run Romex in conduit?

Romex cable cannot be run in conduit because it is not designed to be used in that way. Romex is a type of non-metallic sheathed cable that already has its own protective outer jacket. Running it in conduit can cause overheating and damage to the cable, potentially leading to a fire hazard. It is important to follow the manufacturer's guidelines for proper installation of Romex cable.


Is Romex in conduit allowed?

No, Romex cable is not allowed to be run inside conduit. Romex cable is intended to be used in exposed or concealed applications within buildings. If conduit is used, it should contain individual THHN/THWN wires instead of Romex cable.


How many T-9 cables does it take to supply a ship with 1600 amps?

To determine how many cables are needed, we need to know the maximum allowable amperage each T-9 cable can handle. Once we have this information, we can divide the total amperage needed (1600A) by the maximum allowable amperage of the T-9 cable to find out how many cables are required to supply the ship with 1600 amps.


How thick is the cable to conduct 22.5 kw of power?

Cable doesn't conduct power, it conducts current. Either the voltage and load must be known or the amperage the cable will need to conduct to determine the size of the cable. Once the amperage is known, there are multiple tables online that have cable size and amperage. Do a Google search for "conductor amperage" for examples.


Why are conductors needed?

If you want to operate the conductors maximum capacity, the conductor needs the heat, that the amperage produces, to be dissipated. This is why in the electrical code book there are two amperage ratings. The first one is for a free air rating which allows for a high ampacity of the wire. The other rating is for three conductors in a conduit which confines the cooling capacity and so the ampacity rating of these wires is lowered. The same procedure is used in cable spacings in ladder tray networks.


What is the maximum current capacity of 4 sq mm copper wire?

I can say it is 29 Amps.But again it depends on the cable length.The more the cable length is the less the current carrying capacity will be.
