Does anyone have a picutre of the Leviton 382 push switch not to be confused with the Leviton 9382?
Yes, I have a picture of one. It's a very nice push switch.
Show a Wiring diagram for 2x12 volt batteries in series?
No, but I'll tell you how to do it... Put the two batteries in the truck. Call them "1" and "2." Hook the positive cable from the truck to the positive of battery 1, the negative cable from the truck to the negative of battery 2, and the series-wiring cable (it's about a foot long, and it's got a battery clamp at both ends) between the negative on battery 1 and the positive on battery 2.
Is it OK to use an unpolarised capacitor in a circuit where there was originally a polarised one?
Well... Maybe yes, maybe no. It depends on two things. First, the physical size of the non-polarized capacitor may well be larger than the original size of the polarized capacitor, so it might not fit. Second, you have to consider the RMS current rating of the capacitor. Often, a polarized capacitor, such as an electrolytic capacitor, is intended to be used in a power supply, and is rated for a certain RMS current. A non-polarized capacitor, however, might not be rated for the same or higher RMS current, so it would not be able to handle the load.
Even though you have two like devices they have separate characteristics tailored for each piece of equipment. There are several factors that contribute to the resistance values, such as the amperage ratings. One might be rated at a higher load factor that requires heavier components for it's use. The first thing to come to mind is the overloads. In the motor relay starters there should be a set of heater overloads protecting the motors. They are rated for the individual motors to which they control. You can have two identical devices if one runs a 1hp motor and the other a 2hp then the overloads will be rated close to 125% of the start up amperage's of each motor and will reflect the difference in a resistance test as the 2hp OL's will have less resistance than the 1hp due to size and construction/materials. I have omitted any possibilities of test issues assuming they were both tested identically because the OL's are a series parallel circuit and will give different values tested at different points. Meaning if one device was tested from screw to screw across the OL's themselves and the other was tested from motor terminal to line terminal then the second one will cover more distance and incorporate more values in its readings. Try removing the OL's from the starter relay and test again to see if or what the difference is then. Then test the OL's unattached and any discrepancies should calculate out just be sure to use the correct formula for series and parallel resistance calculations or none of it will make sense lol.
Why transformer is only used instead of any other device?
A transformer is the primary device which transforms voltage to a higher or lower voltage. In electronics, capacitors and resistors perform this function.
How do you test polarity on a boiler?
To test polarity on a boiler set the meter to loop, touch the two leads together, and it will buzz or read as "000". This will show you the polarity as well as test for continuity.
Acceptable voltage drop for 3 phase 415 volt motor?
The voltage drop should not exceed 3% on a feeder or branch circuit.
Check the earth fault trip off set limit of the ACB. It may be too low.
How many circuit breakers would a lightning strike trip?
Generally circuit breaker is not designed to trip off in the event of lightning. The system has lightning arrestors which reroute the lightning effect to earth instantly. If there are no lightning arrestors then the equipment are likely to fail upon a lightning strike.
When capacitor is in the circuit without a load connected what will power consumption be?
When a capacitor is connected in a circuit without a load, the power consumption is essentially zero in a DC circuit, as the capacitor will eventually charge to the supply voltage and then stop drawing current. In an AC circuit, while the capacitor can draw reactive power, it does not consume real power since it stores energy temporarily and releases it back into the circuit. Therefore, the average power consumption remains zero for ideal capacitors under steady-state conditions.
Hazard lights and blinker problems 528i BMW?
If you're experiencing issues with the hazard lights and blinkers on a BMW 528i, it could be due to several factors. Common causes include a malfunctioning relay, a faulty turn signal switch, or electrical issues such as blown fuses. Checking the fuse box for any blown fuses and inspecting the relay and switch for proper operation can help diagnose the problem. If these components are functioning correctly, it may be worth consulting a professional for a more in-depth electrical diagnosis.
Where is the gem module on 05 f150?
On a 2005 Ford F-150, the GEM (Generic Electronic Module) is located behind the dashboard, specifically on the driver's side. To access it, you'll typically need to remove the lower dash trim and potentially the knee bolster. The GEM is mounted to the metal support bracket of the dash. It's responsible for various functions, including lighting and accessory control.
Ungrounded dc supply earth fault location find out?
To locate an earth fault in an ungrounded DC supply system, you can use a combination of insulation resistance testing and fault detection devices such as ground fault relays or sensors. Monitoring equipment can detect changes in voltage or current that indicate a fault. Additionally, the use of megohmmeters can help assess insulation integrity. Regular maintenance and testing are crucial for early detection and prevention of potential hazards.
Troubleshooting electrical circuit for washer pump on Chevrolet S10 2000?
To troubleshoot the washer pump circuit on a 2000 Chevrolet S10, first check the washer fluid reservoir for adequate fluid. Then, inspect the wiring and connectors leading to the pump for any signs of damage or corrosion. Use a multimeter to test for voltage at the pump connector when the washer switch is activated. If there's no voltage, check the fuse and the switch, and if necessary, trace the wiring back to identify any breaks or shorts in the circuit.
How are the fence wires connected on a Sentry 2000 charger?
There are 2 bolts which protrude from the bottom side of the charger. Attach the left side bolt to your ground post with a section of wire. Attach the right side bolt to the fence with another section of wire. (That's how mine is set up.) Easy to use.
What should you do to fix a light which goes out and comes back on by itself all day?
== == Tighten the bulb/plug Make sure both the hot (black) and neutral (white) connections under the wire nuts are solid, and that terminals (screws) are tight. == == <><><> If neither of the above tips help to fix the problem it could be caused by a loose connection anywhere else in the circuit. For example it could be a loose screw which should hold a wire tight in a terminal on a switch that controls the lamp. Always make sure you have switched off your electricity supply at the main breaker before you take a look at those cable screws!
If you don't know how to do that then you must call in a licensed electrical technician to fix the problem as soon as possible because a loose cable screw could be dangerous.
The reason for that warning is this: when the lamp is burning the loose connection is very likely to be getting hot and could start a fire. The danger exists even if the circuit breaker does not cut the current. (It may well not cut the current because it won't be higher than it should be...) Always be sure to switch off the breakers at the main panel
before you attempt to do any work on any mains power circuit. As always, if you are in doubt about what to do, the best advice anyone should give you is to call a licensed electrician to advise what work is needed.
Before you do any work yourself,
on electrical circuits, equipment or appliances,
always use a test meter to ensure the circuit is, in fact, de-energized.

What should do if your surge strip catches on fire?
If the surge strip catches on fire, unplug it from the wall outlet and use a fire extenguisher or sand to smother the fire.
To verify correct wiring you should have: Battery 1 Positive, to Battery 2 Negative, and Battery 1 Negative to Battery 2 Positive is series wiring, combining the voltage rating of both of the batteries. I suggest adding a "Battery Cut-Off Switch" in the circuit. Some slight arcing can happen if you drag the connectors together.
Try doing it outside your vehicle and use a multimeter set to DC volts and test for 22+ volts.
