A Marr connector is a brand name for a wire nut. They were one of the first companies to make a wire connector and the name in the trade has stuck. When joining wires together it is still referred to marretting the wires together. I prefer B-Caps as more wires can be gathered together. Marretts were made in three sizes 31's, 33'sand 35's. Depending on the size of the wires to be joined together will govern the size of the wire nut.
There is a great article on related links below that gives a bit of history as to how they became into being.
All transformers are AC. Your question also does not contain enough information. If it is a multi-tap transformer, the wiring will be unique to the manufacturer but is very often indicated on a label or printed onto the former or case of the transformer. If it isn't a muti-tap transformer, no wires should be connected together, or you have worded the question very badly.
Electrical wire splicing is the act of removing the outer shell of a wire, exposing the inside and connecting to another wire that is also spliced. This also allows you to add length to wiring.
Leave 460 w1 u1 v1 to L1 L2 L3 the 230 incoming low voltage, feed wires for 230v will have to be a heaver wire, Unjump w2 u2 v2,then put a jumper from w2 to U1, next u2 to v1 are jumped together, last is v2 to w1 jumped together. Remember that the 460 wires are lighter wires, the wire gage is a larger number, always check your electrical references, 230v will be a heaver wire or a wire gage with a smaller number....
In house wiring you have hot (Black), neutral (White) and ground (Bare wire).
Primary utility wiring uses an ACSR cable, (Aluminium Conductor Steel Reinforced). The multiple strands of aluminum wires are wound around a center steel cable. The steel center is used to allow longer spans between poles or towers. Ordinary aluminum wire can not be long spanned because its weight would break the wire. All other high voltage wiring is done with different insulation thicknesses dependant upon what the voltage is. The higher the voltage the thicker the insulation. Insulation of the wires stops when the conductors carry kilo voltages usually above 5000 volts.
A ring around wires in a wiring diagram typically signifies that the wires are connected electrically. It can indicate a junction point where multiple wires are connected together. This symbol helps to simplify the wiring diagram and show the connection more clearly.
A black dot in a wiring schematic diagram at a wire intersection represents a position where circuit wires are joined together. At a wire intersection where there is no black dot the wires cross over each other with no junction.
The purpose of the wiring harness is to help keep wires together instead of hanging freely. You can purchase a new wiring harness at any auto repair shop.
easy just tape the cables together.
The Romex color code for electrical wiring is black for hot wires, white for neutral wires, and bare copper for ground wires.
There is no such thing. You must be referring to the wiring harness. If that is the case, it is any bundle of wires taped together or secured by confolute tubing.
If you are looking at a wiring schematic, junction refers to a point where two or more wires are connected together to complete a circuit.
The standard color code for home wiring is black for hot wires and white for neutral wires.
Black wires are typically used for power supply, white wires are used for neutral connections, and green wires are used for grounding in electrical wiring.
Concealed wiring - is any wiring hidden from view. That could be either wires running in a conduit, sealed under a layer of plaster - or - wires running above a false ceiling.
The standard color codes for house wiring are black for hot wires and white for neutral wires.
In house wiring, the standard color code for identifying black wires is black, and for white wires is white.
