Can you tie the neutral wire on a sub feed to another panel to the main neutral lug?
no
What would happen if a 200 amp breaker is used in a 100 amp sub panel?
There are two things to think about here. First of all a 200 amp breaker will not physically fit into a 100 amp panel. This is so designed because the panel buss is not designed to conduct 200 amps before the current is cut off. A 100 amp rating on the panel is the maximum amount of current that the manufacturer states, that can be handled safely. Second if the 200 amp breaker is in the main panel then everything downstream from that breaker has to be rated for 200 amp conductivity. The wire size will have to be 3/0 from the breaker to the first over current device in the sub panel which will be the sub panel's main breaker. The sub panel can not be a load center but will have to be a combination panel. I doubt that the 100 amp sub panel's main breaker lugs would be large enough to connect the 3/0 cable.
What size wire is needed to feed a 125 amp sub panel from a 200 amp panel less than 200 wire feet away?
A #1 copper wire with an insulation rating of 90 degrees C is rated at 140 amps.
Can you had a 20 amp breaker on your 70 amp sub-panel that has already 70 amp total on it that consist of one 50 and two 15 amp breakers and the panel has 4 available spaces out of 8?

What size breaker do you use for a 100 amp sub panel?
A 100-A sub-panel would be fed from a 100-A breaker.

How do you wire a garage sub panel box from a 100 amp breaker in the house main panel?
you propaly can't sub panel from 100 amp panel. Just not enough amperage to be worth while. i had to up grade t a 200 amp main first and then I was able to take a 60 sub panel from that.

Can 100 amp distribution panel feed a 70 amp sub panel?
Yes they can. As long as the total load of all subs does not exceed the rated capacity of the main breakers, you should be fine, including 80 percent de-rating of any constant loads.

Can you feed a 200 amp sub panel from a 200 amp panel?
Judging by your question I'm going to take a guess and say you should probably not attempt to do this yourself. Nor do I recommend it. That being said. You can either have your service upgraded to 200amp, and install a 100amp double pole breaker and branch it off into a 100 amp sub panel. You could most likely re-use your old panel for the 100 amp sub panel. Or... You could have your new 200 amp panel installed in a different location and your current panel wired into it for 100 amps.
Is a 50 amp sub panel enough to do a bathroom and kitchen?
Possibly if the kitchen does not have an electric over and electric cook-top and no eclectic water heater in the bathroom. If they are electric have an electrician evaluate what is being powered in the kitchen and the bathroom to determine if a 50 amp sub-panel is large enough. I would for sure at least go with a 60 amp sub-panel.

I have a Transformer 480 primary 208 secondary feeding 1 200amp mb 42 space panel I need to feed a subpanel 6 ft away I'm thinkin feed through lug at top of bus or at feed through MB suggestions?
The sub-panel need to be fed from the main panel, by way of a circuit breaker connected to one of the breaker locations. Or if your sub-panel has a main breaker installed you can feed from the main panel with a sub-feed lug kit. This looks like a breaker, but is only a point where you can branch off the sub panel.
What is the largest sub panel you can install off from a 60 amp main panel fed by 100 amp service?
If what you state in this question is accurate this is an illegal installation. A 100 amp service can not have any equipment connected to it less that that of the service size. The 60 amp main panel must be a 100 amp panel to be a legal installation.
