A hairdryer fell into the bath. Knocked out traffic jams in the apartment. The hairdryer was disconnected from the outlet and pulled out of the bathtub, drained water. Can I use the bathroom, if not, what should I do?
Will a 10 kW three-phase electric motor work in a three-phase network of a 5 kW house? And will there be an obstacle to the 16A machine installed in the electric meter?
Why arcing of contacts of relays, circuit breakers and magnetic starters occurs. Ways to eliminate and prevent sparking of the contact system.
Why did the phase disappear in the socket, switch or on the chandelier. The reasons for the situation when there is no phase in a single-phase or three-phase network.
There is a stationary dimmer, I want to connect an LED strip to it. I was advised to connect through a dimmable power supply. Can this be done?
There are 20 REV diode lamps installed in the room; transformers that burn out are included. Can I put one transformer OSM1-1.0 220 / 5-82?
The two-key switch has only one key involved, how can one of the lamps be connected to the second key without laying a wire? Maybe there is a relay?
How to connect the unit two switches one outlet? Light on two rooms, we have five wires of the same color, the phase is only on one.

She dried her hair with a hairdryer, a plug was inserted next to the one that turns on the computer, bam - and there is no light in one room, in the rest there is, what should I do?
"Builders" brought out wires to connect the shield low. Input cable 107 cm from the floor. Hang the visor low? Remodel? Or build up, and if so, how?
Good day! I have such a question, how to connect a voltage relay together with a voltage regulator? In what order to connect?
Over voltage has been taking too long for us, reaching 260 Volts. Is it possible to connect a small resistance in the form of an iron pin parallel to the rocket launcher?
When I put my multimeter to measure the capacitance of the capacitor, it shows me O.L. I replaced the batteries, the voltage measures normally. What does that mean?
Street lamp, it has protection class I, requiring mandatory grounding. Is it possible to connect it through a double wire without using grounding?
Can a lamp designed for a 220 volt network be connected to a network with a supply voltage of 110 volts? I wanted to put an ordinary lamp designed for 220-230 volts.
