How do you hook up a 4 wire double pole box from the power of a sub box with no neutral BUS?
If you have a "sub box" with no neutral supplied to it, then you can't safely wire a four lead receptacle as you can't provide the needed neutral, the grounded conductor, to the device your feeding.
On a older clothes dryer that has a three-wire cord where does the bare wire connect in the subpanel - on the neutral buss or the ground?
Answer for USA, Canada and countries running a 60 Hz supply service. WARNINGDo not use 2 conductor with ground cable to feed a 3 prong 120/240V dryer outlet. The outlet is ungrounded, and the third conductor is neutral not ground. Your ground wire must be sheathed by code. You cannot use the bare neutral conductor as ground. Another answerYou should not connect a three wire circuit for a dryer to a sub-panel, it should go all the way back to the main panel. The code never allowed a three wire circuit with a bare neutral to go to a sub-panel. By connecting the three wire cable to the sub-panel you take the chance of energizing the enclosure for the sub-panel if something were to happen to the grounding conductor from the main panel. Four wire circuits were required for dryers anytime they originated from a sub-panel, now the code requires all dryer circuits to be four wire: two hots, neutral and grounding conductor.As always, if you are in doubt about what to do, the best advice anyone should give you is to call a licensed electrician to advise what work is needed.Before you do any work yourself,on electrical circuits, equipment or appliances,always use a test meter to ensure the circuit is, in fact, de-energized.IF YOU ARE NOT ALREADY SURE YOU CAN DO THIS JOBSAFELY AND COMPETENTLYREFER THIS WORK TO QUALIFIED PROFESSIONALS.
Can you tie the neutral wire on a sub feed to another panel to the main neutral lug?
no
Are the neutral and ground bonded in a sub-panel of an out building?
The neutral and ground are only bonded in a sub-panel of an out building if the code requires a buried ground rod or plate at this location.
Can neutral and ground wires be connected to the same buss bar in a service panel?
No. The sub panel is wired that same as an ordinary three wire load. The three wire is connected the sub panels terminal points as red to L1, black to L2, white to the neutral bar and the ground wire in the cable set to the ground bar. The one thing that has to be done is the bonding screw that bonds the neutral bus to the panels metallic enclosure has to be removed. The electrical code states that there is only one place that the ground is joined to the neutral bar and that is at the service entrance point into the main distribution panel.

Where should the grounding electrode conductor and the grounded circuit conductor of the wiring system be joined?
Answer for USA, Canada and countries running a 60 Hertz supply service.The grounding electrode conductor is brought into the main disconnect section of the distribution panel and a connection is made to the neutral block. The terminations in the panel at this point are two incoming "hots" to the main breaker and a neutral wire to the neutral terminal block. In the neutral termination block there is a ground screw that screws through to the distribution panels metal enclosure, there by making the metal enclosure the same potential as the ground plate or rods and the neutral wire that comes in from the street. The grounded circuit conductors of the wiring system are terminated on a separate ground buss that is located in the circuit breaker section of the panel. This buss is bolted directly to the rear of the distribution panel's metal enclosure in the circuit breaker section of the distribution panel. This ground buss is at the same potential as the ground electrode conductor above because of the grounding screw that connects the neutral block to the metal enclosure. Code requires when wiring sub panels within the same building that the neutral block screw be taken out of the circuit and a separate ground wire be run directly from the main distribution panel. This is to prevent any short circuit currents from the sub panel traveling back on the sub panel feeder's neutral wire.
Do the grounding conductors and bonding conductors ever connect to a common point?

Your neutral bus is "bonded" to the Ground bus only at the main panel. When you run branch panels you do not connect neutral to ground in these branch panels, only the main panel. There is typically a screw in an electric panel where the bonding occurs.

When I disconnect the neutral wire from sub panel still have juice in the gfi outlet When i connect the hair dryer to the gfi without the neutral it works and the light in the bathroom turns on?
You have some serious wiring problems, for sure. My first guess is that your grounding conductor and neutral are touching somewhere and your ground is acting as the neutral when the neutral is disconnected. The light coming on when the hair dryer is used is another mystery. You need to hire a competent electrician to trouble shoot these problems.
How do you make floating ground in 100 amp sub panel Sub panel 30' from main panel and is grded to 2nd 10' rod wired to 1st 10' rod at the main panel. GFCI bkrs are nuisance tripping in bsmt location?
If the sub panel is in the same building remove the bonding screw that bonds the neutral bar to the panels enclosure. Remove the ground from the second ground rod. The sub panel is grounded by the ground wire from the sub panel's feeder. If the panel is separate from the main building treat the sub panel as a separate service. It will need its own ground rods and ground wire from the rods to the neutral bar of the sub panel. Leave the bonding screw in. There will be no ground wire in the conduit between the two services.
How many sub panels can you have off an 100 amp 2 phase residential service?
The key is that you still only have 100 Amps to work with. You could have multiple small panels if needed for convenience, but the total capacity for constant load should not exceed 80% of maximum or 80 Amps. Also make sure neutral and ground only bonded together at main panel.
What is the neutral particle found when atoms share electrons?
The neutral sub-atomic particles in an atom are neutrons and they are found inside the nucleus.
