New Electrical Work

XHHW type insulation is commonly rated as sunlight resistant. However, this is the XHHW-2 type of insulation that is commonly used in conduit and other raceways.

No, these are two different distribution systems. The North American system uses 60 Hz and the European system uses 50 Hz.

Yes, any flexible conduit that has live wires drawn into it must have a ground wire also installed with the "hot" conductors. The reasoning behind this rule is that the flex in the conduit is coiled and has a long length to it. The continuation of the grounding medium through the tightness of the conduit connectors to the flex was not considered a properly secured grounding system so to overcome this weakness in the grounding system, a ground wire now has to be installed.

Yes, it is perfectly safe. An outlet is just a place where electricity is available when you need it. It can do you no harm whatsoever by sleeping next to it any more than sleeping next to a electrical cord plugged into that outlet and then run up to a lamp or clock next to your bed. I assume you are worried about the magnetic field created. This field is so low that it is barely detectable at an outlet.

Either #3 Copper or #2/0 Aluminum.

Outside breaker distribution panels must be rated for outdoor use and are already weather proof. If this is not the case then a protective covering must be made around the panel to keep the weather elements away from the box. If either of these options are used then the distribution box does not have to be caulked.

Like any Automatic Transfer Switch, wiring ATS not easy and not difficult. It requires a qualified electrician to wire it properly. You can read more about wiring an Automatic Transfer Switch in the related link.

There are zero watts in 130 amps. W = A x V. Without a voltage stated the wattage can not be calculated.

To calculate an answer a voltage must be stated.

No, there has to be a three foot clearance in front of the panel. This is so that electricians can work safely on the panel.

The distance between electrical outlets in a home will depend on what country of origin you're from and also what type of power supply service you have. In the United States and Canada, that run on a 60 hertz power supply service, the general rule of thumb is spacing of about 12 feet between each outlet along the walls of your home. The distance between outlets around your kitchen counters is much shorter. About 4 feet of space is required between each plug.

Not a good idea. Install a back board. A backboard of 4' x 4' is of ample size to install the panel and anything

else that needs to be mounted. A thickness of 1/2" is OK but 3/4" is perfect. Some times telephone and cable companies need mounting points and this board is just perfect for this.

No, a Cutler Hammer will not work in a GE panel or vice versa.

The smallest size breaker is a 15 amp and with a #14 wire which has a capacity for 15 amps and a 120 volt source, this combination will give you the capacity up to 1800 watts. W = A x V, 120 x 15 = 1800.

Insulated wire is not used for high voltage installations. For transmission installations ACSR is used. It is Aluminum Conductor Steel Reinforced cable that is strung from tower to tower. The insulation comes from the separation of the conductors and the amount of insulators that support the wires from the tower frames. Common insulators have a rating of 5000 volts. To get to higher voltages they are strung together boosting the insulation rating by 5000 volts each time another insulator is added to the string.

Unless you do not have enough space in the service panel it is always a good idea to have each room on it's own circuit. If you want to put 2 rooms on a circuit just make sure those 2 rooms do not overload the circuit and wire it for a 20 amp circuit. Two bedrooms with 8 outlets each and 1 light each is about all you would want on the circuit. I would never put 3 rooms on the same circuit.

Wire in conduit for underground feeders has to have an insulationrating for wet and damp locations. In the marketplace there is also wiring thathas an insulation rating for direct burial that does not need to be installed into conduit.

16-gauge wire has a diameter of 0.05082 inches.

A breaker is sized by the wire size. The wire is sized by the amperage. The formula for amperage is I = W/E. Amps = Watts/Volts. As you can see with no voltage stated an answer can not be given.

It depends on the wiring, the current load in the wiring , and the distance. The NEC Code book has the charts for this.
And the size of the conduit.

I am taking this question to mean that you are making an installation using two wire cable that has a black and white in it. In this situation the white is not called a neutral. At the distribution panel end the white wire does not connect to the neutral bar. It will go to one side of a two pole breaker. the other side of the breaker will connect to the black wire of the cable. On the 230 volt receptacle end the two wires will connect to either side of the receptacle. Make sure that the cable wiring is rated to take the amperage that your plug-in device will draw. The last thing to do is identify the white wire as a "hot" current carrying conductor. This is done by placing black tape around the white wire. This is done at both ends of the cables white wire. This is done to ensure in the future that is someone else works on the circuit they will know that the wire is not a neutral conductor.In the market place there is a new cable that has no white wire in it. This cable is used for wiring baseboard heaters and has a different colour jacket to identify the type of cable it is. The internal wiring colours are black and red. This wire is used for all 230 volt circuits.

No; drawing more than the rated amperage from a transformer will cause it to overheat.

Wire is sized by the amperage of the load. Without knowing what the load amperage,the voltage and whether the load is three phase or single phaseat the dock, an answer can not be given.
