NO stands for Normally Open and NC is Normally Closed. It references a switching application. It is the base state of the switch. So if the load is connected to the NC terminal it will usually be energized and when the switching device is activated the circuit will open and the load will be de-energized.
The NO terminal would have the load de-energized until the switch was activated and then it would be energized.

Where does the red wire in a baseboard heater connect to the black or white wire in the wall?
In the heater you will have two wires. You should then have 2 supply wires from the panel, and 2 wires from the thermostat. The neutral (white) supply wire should go to one of the wires on the heater. The hot (black) supply wire should connect to one wire from the thermostat. The other wire from the thermostat will connect to the other wire from the heater.
How do you connect grounding of i and c?
Grounding of I and C? to ground something is to have a wire that goes to a grounded connection the bare wire in a normal wire set.
How do you connect float switches for a single phase motor through contactor and Over Load Relay?
you would wire a float switch into the control circuit i.e, the contactor coil (which is relatively low current but rated at least for the control voltage,, in most cases 120VAC). also in the same circuit would be the overload contacts. if the overload trips and/or the float switch opens then voltage is removed from the contactor coil
Why do we need a complete circuit for the bulb to light?

Can you connect a 6mm earth wire to a 2.5 mm earth wire?
A 6 mm earth wire can be used to replace a 2.5 mm earth wire, but if there is an existing 6 mm earth wire it must be 6 mm all the way to the earth, and not replaced by a smaller wire between it and the earth connection.
How does a wire connect to a bulb?
A wire connects to a bulb by attaching one end of the wire to the metal base of the bulb and the other end to the metal contact on the bulb socket. When the circuit is complete, electricity flows through the wire and powers the bulb, causing it to light up.

How do you connect 4 wire timer model tmdf702zh2?
To connect a 4-wire timer model TMD-F702ZH2, first identify the wires: typically, two for the power supply (live and neutral) and two for the load (common and normally open or normally closed). Connect the live wire to the timer's live terminal and the neutral wire to the neutral terminal. Then, connect the load wires to the appropriate terminals based on your desired operation (NO or NC). Finally, ensure all connections are secure and power on the timer to test its functionality.
How do you wire a sub in a Saturn sc?

What is hot in nc no com in term of electrical wiring?
It appears that "nc no com" may refer to the "normally closed (NC) and normally open (NO) contact" terminals on an electrical device or component. In terms of wiring, these terminals are used to control the flow of electricity through a circuit. The specific wiring configuration for NC and NO terminals will depend on the intended function of the device or circuit.
How to connect a 3-wire LED light to a 2-wire system?
To connect a 3-wire LED light to a 2-wire system, you can use a resistor to bridge the extra wire. Connect the positive wire of the LED light to the positive wire of the system, and the negative wire of the LED light to the negative wire of the system. Use a resistor to connect the extra wire of the LED light to either the positive or negative wire of the system. This will help regulate the voltage and ensure the LED light functions properly.
