For the typical size (I think 18cu. in. box), you can fit 9. Look inside the box on the back wall. it should list how many wires you can have in the box for different gauge wire, typically for 14awg, 12awg and 10awg wires, e.g. 9/14.
To count the wires: 1 for each white, 1 for each red, 1 for each black, 1 for all the grounds, 1 for each switch, and 1 for each outlet.
Example A: the box has two 14-2 wires for power and one 14-3 for the 3-way switching, and one 3-way switch: 3 whites + 3 blacks + 1 red + 1 for all ground wires + 1 switch = 9
Example B: two 14-2 wires and one outlet: 2 white + 2 black + 1 for ground + 1 outlet = 6
Not all electrical boxes are the same size or rating so look at the specs to see how it is rated.
As many as you can easily fit inside.
If one circuit contains all three switches and their loads are on the same circuit then only one "hot" and one neutral is needed.
No good way to answer this. A 3-way light switch has one wire coming to it, two wires run to the second switch and one back out of the second switch to the light. At any point, any one of the terminals may be "hot". The only one always hot is the first single terminal that is the power source.
If single phase - 2 wire service > two wires If single phase - 3 wire service > three wires If three phase - 3 wire service > three wires If three phase - 4 wire service > four wires US residential service is usually single phase 3 wire service: Two hots and neutral.
If a light or set of lights is able to be switched 'on' and 'off' by more than one switch then those switches are 3-way switches. 3-way switches will have 3 screws on the sides for terminating wires as opposed to 2 screws on a regular single pole switch. 3-ways will typically have 2 brass screws and one black screw called the 'common'.
Several ways, if you have hot going to the switch,make a pigtail off of the hot and make two hots, one for each switch, then you have two hots going out, one for each fan. A single pole duplex switch,is two single pole switches mounted onto one frame. So it is the same as wiring a fan to a switch, this case you have two fans and two switches. There is usually a wiring diagram with the switch. Hot wire to brass screw, silver is the hot leaving the switch going to the fan. Your neutral, just runs through the box to each fan, there are so many way to wire this setup it would fill a page,so I'm just giving you one idea, I have no clue if you are installing all the wires or there preexisted.
Answer varies. Is it a deep or shallow box? is there a receptical, a switch in the box as well? is it just a junction box? are they single wires or NM cable?

There should be 2 or 3 wires. A hot, a neutral and sometimes a ground.
I stands for CURRENT. Many times a on/off power switch will have a I printed on it.

4 wires are needed.positive battery cablenegative battery cablepower wire to starter solenoid (momentary switch)ignition power wire (on/off switch)
A bulb must have a minimum of 1 switch if there are 2 batteries. The batteries can be connected in together via wires to prevent the need for a second switch.
There is only one ground wire needed on any motor, single or three phase.
Their have been many technicians that have been seriously injured doing exactly what you are asking.
