Wiring A Bathroom Exhaust Fan With Light
When you want to learn more about How to Wire a Bathroom Fan and Light on Separate Switches to do it yourself at home, we are happy to give you a detailed breakdown of how to do this. So, stay tuned for this article!
But for your switches to be more optimized, you first need to know the rules when installing the switch and the scheme to install before you can proceed with how to wire a bathroom fan and light on separate switches.
Rules to arrange switches, electrical sockets in the bathroom
Most modern bathrooms need enough outlets for appliances such as hair dryers, trimmers, electric brushes… Besides, you need to write down items such as Jacuzzi, heater, ventilation fan. , even the washing machine.
Jacuzzi and shower sockets can be installed behind the wall as these don't need to be plugged in and pulled out as often. Next to the bathroom mirror (usually above the sink), you should have two sockets for small, frequently used appliances such as hair dryers, trimmers, electric brushes…
If you intend to put the washing machine in the bathroom, create a separate space and arrange more sockets. Note, the socket for the washing machine should be located 50-60cm away from the faucet.
- The underground wires to the sockets and switches must originate from the horizontal trunk and the line should be arranged vertically with the electrical panel, switch, or socket.
- The power cord must be at least 10cm away from windows and doors.
- The main light switch should be located near the door at a height of 70-90cm.
- Light switches in the storage room should be located on the corridor wall.
- Switches for bedrooms, dining rooms, and kitchens should be located inside each room.
- Sockets in the rooms should be located 30cm from the floor, switches 90cm from the floor.
Finally, sockets and switches in bathrooms must meet standards of durability, insulation (protection class IP44) and must be properly grounded.

The isolation of lights and fans by adding a two-button switch is ideal to connect fatigue fans in the kitchen or bathroom. The lamp is turned on one key and the second is for ventilation separately. This ventilator attachment is most widely found in homes because it only causes the ventilator to be enabled if appropriate.
Partial selection is adequate for general-purpose PCBs by adding a further jumper to the jumper. A set of 4 controls that are not sold here can also be seen. The drawback is the somewhat tougher nature and heat radiation.
It's not hard to connect a toilet or a bathroom fan, so you can start attaching it to yourself safe after you buy the fan. Only make sure you switch off the necessary circuit breaker in the electric panel and start operating only after checking that the power cable has no voltage.
If connections are good, please replace the fan. Check the relay if the sensor is in good condition and the fan is running. Unplug the relay and check the connectors for power off. Both relays must be powered by one terminal.
Otherwise, there may be a malfunction with the wiring from the fuse to the relay under the back of the fuse box. It is possible that the pin is ejected or the wire is burnt. If there is electricity, replace the relay and try again. One of the relays may have caught fire. If the fan still does not work, replace both relays.
The choice of configuration depends on the type of space and the fan model you have selected to attach the fan to an apartment or private residence. Remember, any scheme includes connections in the ground-to-the-ground 3-wire wires, but if you are fitted with the old two-wire conductors, everything is connected in the same way – just wires.
Substitute the burnt relay while this works. It's rarely a computer problem, but a computer problem should not be ruled out. A power-resistive potentiometer can be used with the simplest controller. That's the resistance paradox. We have picked a resistance of 100 Ohm with a loss power of 4-5 W. You are surely curious why so many watts if the previous resistor has a power loss of two watts.
For example, 4 W of all resistance paths for a potentiometer is set to half, so the capacity loss is half that of 2 W for 50 ohms.

How to connect the electric circuit of the fan in the bathroom
To connect a fan in the bathroom or toilet, it is best to simply turn on the fan simultaneously with the bathroom lighting.
The zero and earth from the two-circuit junction box are directly connected, and the phase from the same helix behind the switch, from which the phase wire goes to the bathroom lamp.
The fan can be connected in parallel with bathroom lights. To do this, we only need to get from the phase, not ground to the fan connection.
The potentiometer has 3 outputs, the output in the middle is the rider and between them and one of the external outputs is the potentiometer. Find detailed graphic material in the backgrounds.
The advantage of this controller is that the speed controller is easy to design and maintain. The downside is the higher cost of the power potentiometer and the radiant heat, as well as the preliminary resistance.
The following circuit is classic among speed controllers. Add a resistor and low-power potentiometer. The maximum possible output voltage of 5 V, that is, 85% is sufficient.
The minimum voltage is 25 volts when you take 7 volts from it, which is lost on the input protector, at the fan input, and for the fan electronics itself there are about 6 volts and at this voltage, the fan circuits are completely idle and the nearly consumed fan is inactive and turned off.
According to this diagram works with the lights on at the same time, the fan will start and work. But such a scheme is not very convenient, because after turning off the lights, the fan will stop working, there is no time to remove unpleasant odors.
But do not worry, we have a better plan is to use the wiring diagram to connect the fan and bathroom with its switch.
Wiring schematic diagram for fan connection from two control switches
For connecting exhaust fans in the kitchen or bathroom, it's perfect to separate lights and fans by installing a two-button switch. One key turns on the light and the second key – separate for ventilation.
This connection scheme for the ventilator is most commonly used in apartments, as it allows the fan to be turned on only when needed.
Power controller
One way to create a controlled source with low heat radiation is to build a convertible voltage converter. There are several of them on the motherboard, CPU power supply, memory voltage. The main downside is the complexity of the design, we will devote a different approach.
The scheme of connection via a two-button switch is a bit more difficult to implement. The phase from the box is connected to the switch, then passed through two contacts and goes separately to the lamp and fan.
Air and ground (not shown in the diagram) go directly from the terminal block to the lamp and fan. To connect according to this scheme you will need to place a separate third wire from the switch to the fan, but it would be more correct to place a three-core cable from the switch to the junction box and connect the fan with a separate cable from the box concatenation.
A simple and widely used lossless power control technique is pulse width modulation. This is nothing more than a periodic switching of voltage with a certain rate of time change when the voltage is turned on and off.
The advantage of this method is simple, just define the switching frequency, choose the lowest frequency that the fan will rotate smoothly.
And the switching frequency can be a drawback, depending on the design and quality of the fan coil unit, it can cause frequency sparks of the coil. And speed control doesn't work without an additional controller installed.
Instructions on how to wire bathroom fans and lights on separate switches
The types of electrical wires used in the home must always put safety first. Therefore, bare conductors must never be used but must be conductors with good quality insulated sheath.
Indoor conductors must not use bare conductors but must use conductors with good quality insulation. The size (cross-section) of the conductor is chosen so that it is capable of carrying the current to the electrical tools it supplies, the small-cross-section conductors should not be used to power tools with a too large a capacity to avoid causing a house fire.
The 2-way switch is a device commonly used in civil electrical networks, applied in the installation of circuit circuits, electric circuits using 2 switches to control 1 lamp at 2 different positions. So this article will guide how to connect the wire to a 2-way switch.
Wiring has many ways to wire a switch. The popular way that many people choose and use is: for running complex power cord, connecting to control circuit, a load of the power switch. But with this method and this way, there will be a disadvantage that is wasted power.
The second method is used by many people because you have to use a very little amount of wire compared to the first method. However, many people say that this way, it is not guaranteed when the two terminals to the electrical equipment are phase wires.
The working principle of this method is: when current occurs there is a voltage difference. When the two ends of the device are 2 phase wires or 2 neutral wires, there is no current flowing through the device and does not affect the life of the electrical equipment, but brings the highest economic efficiency to the user. electrical equipment.
Conclusion
In this article, you can wire the wiring in two ways and each has different execution, we hope you will be able to perform wire a bathroom fan and light on separate switches for space you.
