Current carrying capacity is different for aluminum from that of copper cable. Under different conditions like, type of insulation, number of conductors, in conduit, underground, in air, single or multilayer, system voltage, the current carrying capacity varies a bit. Hence You must refer a standard chart from a reputed cable company.

On a three wire supply system if you connect the two 110V wires together and they are across the phase they will short out and trip the breaker. If the two 110V wires are supplied from across the phase and connected to a motor then the motor will run. If the 110V wires are on the same phase nothing will happen.

This is just a charge that accumulates on something that is isolated from ground. Under some circumstances a charge may build up on your body and then you touch something that is grounded and you get a shock. This is the static electricity flowing to ground.

I was a US Government employee. Me and my family were sent to England where we resided for 7 years. We shipped all our household goods with us including all our US electrical appliances. Once there, we purchased transformers which come in various wattage ratings. The transformer actually converts the 220voltage down to the required 120 volts for US products. Anything with a motor would only be turning at 50 cycles a second vise the 60 cycles of US current. This would only affect the playing speed of say a record player (obselete now) but radios, toasters, coffee pots or anything of that nature would work fine. Hope this has helped.

You need a transformer, as mentioned above.

Note that for running UK appliances in the US that is not necissarily true, as the US has 120/240V service. You'd just need a special outlet for your 240V appliances.

Some, but by no means all, electronic appliances have 110/240V switches to allow use on either system.

As a rough estimate, for medium voltage cables directly buried in earth, I use 2 A / mm^2 for copper conductors, and 1.2 A/mm^2 for aluminum conductors.

However, the installed capacity of a cable is mostly dependent on how much heat can be dissipated to its surroundings, and ultimately the maximum temperature of the insulation material.

For this reason, it is important to know how the cable will be installed, what conductor is used (Al or Cu), the cable insulation (for both thickness and operating temperature limits), soil thermal resistance (if buried), and if there are other heat sources (cables, process pipes, incident solar radiation, etc) are nearby.

There are several cable manufacturers that provide reference current ratings for nominal installations. Check Nexans, Prysmian, or Okonite (US dimensions).

A power adapter Typically is an item that converts a 120VAC power signal into a much safer and lower DC signal that can range anywhere from 2 volts to 30 volts. Inside its guts, There is most likely a transformer, resistors, rectifiers, and Chips that control the current.

In case you do not understand,let me break it down:

120VAC enters into the adapter.

it enters into a step-down transformer.

this lower current enters a series of rectifiers that convert AC current into a safer and cleaner DC current.

This DC current enters a few resistors along the way.

Finally, this Much lower, cleaner, and safer current is transported out some wiring and to your laptop or other portable electronic.

2.5 sqmm cu cable current carrying capacity is 19 amps.

The average dehumidifier can cost anywhere between $100 and $200 in electricity per year.

The 5 amp fuse has many wattages that it can protect. It depends on the voltage of the circuit that the fuse is protecting. Use the following formula, Watts = Volts x Amps. For example 120 volts x 5 amps = 600 watts, 240 volts x 5 amps = 1200 watts, 480 volts x 5 amps = 2400 watts and 600 volts x 5 amps = 3000 watts.

Boiler mountings are different fittings and devices which are necessary for the operation and safety of a boiler .e.g. pressure gauge, safety valves , steam stop valve etc Normally these device are mounted over boiler shell .Boiler Accessories are auxilary plants or parts required for steam boilers for their proper operation and to increase efficiency of the boiler .e.g.feed pumps, super heater , economiser etc

You can use a voltage meter. A fully charged battery of 12v should read 12.6v with negative cable disconnected, and all accessories off. It should not fall below 12.4v when fully charged. This is the easiest way to check.

Electricity, or AC (alternating current) runs in cycles. It has a positive and negative cycle. One cycle is also referred to as one hertz. In electronics a cycle is also known as a hertz. So when referring to 60 hertz, look at it as seeing one cycle 60 times in a second.

By rule of thumb, the neutral conductor is half the size of main conductor.

The equation that you are looking for is I = E/R. Amps = 120/20 = 6 amps. This is one of the basic equations of Ohm's Law.

Mains electricity is nothing but main source of power in an installation. From the mains the power is then branched out to different end usage.

Ring connection of socket outlets? Have no clue what you mean by this. Please rephrase the question in terms that are understandable. I will venture to guess as to what you mean. If you mean what is the advantage to connecting more than one outlet on a circuit the answer is to save wire and to allow the installation of over 100 outlets in a home on maybe just 10 circuits depending on the use of the outlets.

An ordinary bath takes 4-6 units of electric energy and it's usual to have a hot water tank with a 3 kW immersion heater, so it would not be instant for that amount of energy.

But there are instant heaters for showers because they use less energy. A power-shower runs at around 8-11 kW and if the shower takes 15 minutes that would use 2-3 units.

If the 2 amps is the output amperage of the power supply, the maximum that should be drawn from the unit is 2 amps. The load amperage that is connected to the power supply should govern the amperage of the fuse used. There is not much range there, the fusing could go from .25 to 2 amps.

If the input amperage is 2 amps then the input and output voltage of the power supply should be stated.

No, the only way that the electric bill can be reduced is to reduce the amount of electrical energy used.

It would be impractical to mount them high upon the wall. The child would then just pull on the wire connected to the outlet. Besides modern outlets are childproof and are required in all new homes by the Electrical Code. Older outlets can be made childproof by installing a simple plastic cap.

There are zero watts in 220 volts. Watts are the product of amps x volts. To receive an answer, the amperage of the device has to be stated. This amperage multiplied by the stated voltage will give you the wattage of a device.
