Electrical Troubleshooting

The maximum distance of a wire drop between a service pole and service connection is undefined, as it depends on many factors not included in the question. The information needed to actually compute such a distance includes, but it is not limited to, the service volts, the service Class (60, 100, 200, 400 or more amps), and whether or not the drop involves a mid span tap -- that is, the service is actually connected not to a pole, but it is connected to secondary wires between two poles.

A utility company will usually bring their service a maximum of 100 feet on to private property.

Quite a bit of bad stuff can occur, simultaneously, when a person is electrocuted.

The first is muscle energy depletion. When muscles are electrically stimulated they go into spasm and deplete the sugar reserves, making it impossible for the muscle to continue to function. When that occurs, it may be possible that the heart muscle can no longer pump. That's why it's important to know CPR, so that the heart muscle can receive energy in the blood that's being pumped.

Second can be bone fractures. Muscles are capable of contracting so violently that bones will sometimes fracture under the strain.

Third is electrolyte imbalance. Nerves are the communication mechanism of the body and there is a balance of electrolytes between the inside and outside of the nerves. When electrocution occurs that balance can be drastically modified, sometimes permanently.

Fourth is tissue damage. High energy electrocution can literally "cook" the tissues; muscle, bone, ligaments, nerves...

Take the oven to an appliance repair shop. It sounds like the door safety interlock has jammed the opening mechanism.

If a 200 mA power supply is used on a circuit needing 2 amp it would overload the power supply. Two amps equates to 2000 milliamps. Trying to pull 2000 milliamps from a device that is only capable of supplying 200 milliamps is not advisable. The excessive current draw would most likely burn the wires open and render the power supply useless.

Insulation resistance.

The current path in an over current fault is the path of least resistance. Older electrical systems used to use the neutral wire for this purpose. It was found that on some occasions this was not the path of least resistance. Hence the installation of a ground wire being installed in cable sets. This innovation caused the whole grounding section in electrical code books to be rewritten. Now a specific ground wire is used to bring the fault current back to the distribution panel to trip the breaker and open the faulted circuit.

Analogue sensors are usualy more accurate :P

You should always repair or replace faulty house wiring.

If the over-current protection of a breaker has stopped functioning, you run the risk of burning down your house.

If the ground-fault protection of a breaker has stopped functioning, you run the risk of accidental electrocution.

you can take a siren from a home security device, not a speaker but a siren cause a siren works of voltage and a speaker works of wattage. take a battery that is capable of working the siren then just put the the siren in series with the battery and then take the two wires and put one on the open side of the battery and the other wire on the open side of the siren. If the siren goes off there is continuity between the two wires your testing if the siren dont then there is no continuity.... good luck..

Depends on the chemistry.

A standard D cell has 1.5 VDC. Oxy Nickel Hydroxide and Lithium cells have a slightly higher voltage of 1.7 VDC

NiCd or NiMH rechargeable then 1.2 VDC at full charge.

I would let "direct" mean "linear." The answer then becomes simpler; direct proportional may mean a relationship like 1-1, 2-2, 3-3, etcetera. Proportional by itself would then be free to indicate other proportions; like 1-1, 2-4, 3-9, etcetera -- in an exponential proportion.

Work of some sort depending on the device being powered. For example, an electric car can transport people from point A to point B.

foil, toil

This is a 240 volt, two chimney heater (1500 watts per chimney) with a double pole thermostat. If the heater is not heating at all, indicates thermostat or electric source issue, if one element is heating and second is not, indicates one of the elements is burned out.

or somebody is trying to break in your house

A: braided

B: Solid

C: Standed

current has five effects. 1. physical effects

2. xray effects

3. heating effects

4. chemical effects

5.magnetic effects.

You would need to take the "input" wire for the shunt trip breaker to an electrical switch (not alarm initiating switch, which are DC voltage rated) within the Automan unit and connect to the "Common" connection and the "return", the wire to the actual shunt circuit of the breaker, from the "Normally Open" connection of the switch.

When the unit activates, the switch will be placed into "Closed" position, therefore completing the circuit and activating the shunt coil.

Test according to the procedure in this article.

If the window motor is getting power, replace the regulator assembly.

If it's not getting power, you've got a broken wire--most often in the hinge area of the door.

Or, you've got a bad master switch

Duty cycle is a measure used to describe the symmetry of a square wave and refers to the percentage of the time that it spends at high level. For example if you have a 1 Mhz square wave the period will be 1us and if it is at high logic level for 0.5us and low for 0.5us, that will have a duty cycle of 50%.

You can download a wiring schematic for the John Deere GT262 tractor from the official John Deere website or their online parts catalog. Additionally, websites like TractorData or forums dedicated to John Deere equipment may offer schematics or links to resources. You can also check online retailers that specialize in tractor manuals and schematics.

Either one can be used. Electricians prefer to use a solid wire and use the screw terminals rather that the pressure terminals. An eyelet can be formed with solid wire where as using stranded wire takes a bit more preparation to use. The stranded wire has to be wound tighter at the termination end. This is so that when the stranded wire is tightened under the screw terminal the wire does not splay into individual strands some of which do not get under the terminal screw. With some of the strands not tightened under the screw, this is the same as using a smaller size wire. The breaker feeding the receptacle is matched to a specific wire size. The now smaller wire size has a breaker greater than the ampacity of the wire. This could lead to overheating of the wire under full load and eventually cause a breakdown of the insulation. Once the insulation has broken down, the breaker will trip due to a short circuit. This wire will have to be replaced. This could involve opening the wall board to remove the burnt wiring should this happen.



Most residential wiring is done with solid copper wire. In industrial applications, stranded THHN wire is used because many wires are run through conduits from service boxes and many different colors and gauges can be run to different locations. I personally would not use stranded in a residential application.

Put an ohm meter across the coil and read the resistance. Usually they are quite high depending on the voltage and the size. If you can compare with an known good one then you can know what to expect give or take say 15%. If there is no reading it is open circuited and if it is very low then it has a short within it. Some times the smell will show a short.
