This depends on how many outlets you will need in the home.
It depends on the use of the 10 outlets. 20 amp is the norm. If this is in a shop with heavy loads then you would have to break them up.
It depends on the size of the boards.
Just plug in all of the light sets in to the outlets on the provided extension cord.
If they are on the same circuit you only need 1 neutral wire in the circuit.
Depends on where your home is. In the middle of a city, maybe not. My home is in the country, and yes, we do.
There is no way to accurately answer this because it depends on so many factors. It depends where your water systems are and if you'll need to extend them. It depends how large and what materials you use. It depends on where the waste pipes are and if you need to extend them and so on. You'll have to ask an architect who has the plans of your home.
Minimal 100. Depends on load draw of home. Can be 200 amps or 400 amps as well.
No, it can be on a circuit with conventional outlets.
Two 20 Amp circuits with the outlets staggered so a different circuit is on two adjacent outlets. Should be GFCI protected.
No. The voltage is the same but you'll need an adaptator to use either the English or the European electrical outlets.
That depends. If said patio was constructed prior to GFCI code requirements, then no. If constructed after code requirements, obviously yes. In any event, if you have the opportunity to enhance safety by adding GFCI outlets, even if not required, do it. You can get them for about 13 bucks at your local Home Depot, less in multiples.
Zero. 60A is far too high to power outlets directly. A fire will start far before the breaker blows. What you can do is use the 60A line to power a subpanel, and break the 60A line into 15A branch circuits to feed the outlets. As for the number of outlets you can install on that, you need to sit down and calculate your power needs. What do you plan to power with this? Where do you need outlets? What are your future needs? If you can answer these questions you know what you need. Remember the rule of thumb: your expected load should be no more than 80% of the breaker's capacity. I like the analogy of faucets on a pipe. You can put as many faucets as you want on it, but how many you can use simultaneously is another story. There is only so much water coming into the pipe for so many faucets. Same thing with outlets. You can put as many as you want on a circuit, how many you can use simultaneously safely is another story.
