Anonymous users2024-01-24V requires that the lamp and the fan do not affect each other and can work independently, so the lamp and the fan should be connected in parallel, and the respective branches have a switch control, and there is no switch on the trunk road, so choose A
It is recommended to choose according to the motor wiring diagram, and there is no need to change the capacity casually. If you can't find the original picture or capacitor, use it, and the withstand voltage is more than 400V! Hermaphroditic CBB capacitors. Using 1uF is very large, no matter how big the motor is, the heat is serious!
Panasonic Masano are still relatively good is a bit expensive My home Orida ventilation fan noise is also relatively small cost-effective I highly recommend it Hehe just as a reference I hope it can help you.
Your question is a bit strange, generally speaking, the installation of exhaust fans in the bathroom is divided into ceiling pipe exhaust fans and partition wall exhaust fans, so if it is a ceiling pipe exhaust fan, then it is the height of the ceiling, generally about meters, this height can not be adjusted, according to the height of the ceiling to decide, basically has no impact. The second situation is that the exhaust fan or window exhaust fan installed on the partition wall, in principle, is installed to a position of more than 2 meters, and the ceiling is 20-30 cm lower, so that the hot air is easy to go up, and is pumped out of the bathroom, which is conducive to air convection, so the bathroom ventilation fan is generally installed at a height of more than 2 meters above the ground, and the static electromechanical technology will provide you with a solution to your questions during the installation and use of the exhaust fan.
It is still more convenient to replace the exhaust fan, the key is that you need to understand electricity. >>>More
There is no norm for this, but there are a few principles to grasp: >>>More
