Can you connect two wires to one main lug in a panel board that is only rated for one wire?
This is not a good idea. You don't say what type of connection, but it is typically against the electric code to exceed the designed connection specification.
How do you wire a circuit panel?
This type of question usually means you aren't ready to do this yourself. Study some electrical material and the National Electrical Code and work this answer out for yourself. If I were to give you an answer, you might attempt to do something you shouldn't be doing, and that may cost someone a shock, a home fire, or their life.
Where are neutral and ground wires usually bonded together?
Only in the main electric panel.
Does the common and ground wires hookup together on main box?
Yes, just at the main panel and not subpanels. The bonding of ground to neutral may be a screw or strap.
What are the required for electrical panel?
The main items required for an electrical panel include the panel box itself, fuses, and wiring. The wires are fed into the box and attached to a series of circuit breakers to allow electricity to be directed as needed.

Should wires come in the top of a panel box?
They can come in the top or bottom whichever is the best. <<>> If the distribution panel is a load center (no Main disconnect) the above statement is true. If the distribution panel is a combination panel (main disconnect at top of panel) then the load feeds can only be brought in the two sides and the bottom. A combination panel has an internal barrier to separate the main disconnect from the load side of the distribution board.
What is a sub main distribution board?
A sub main is a distribution board fed from the main distribution board panel normally protected via a CPD.
Can you connect final Distribution board directly to Main Distribution Board without Sub main Distribution Board and why?
yes no problem

How do you disconnect dryer wires outlet for good?
Remove the breaker in main panel and either remove wires from main panel or cap off wires with wirenuts and label for possible future application. Put a breaker filler strip in hole left by missing breaker. At outlet you can just leave outlet or remove from wall and repair hole in wall. If you remove outlet and leave wires in wall it is best to totally remove wire from main panel.
Is it OK to have 250 A of breakers in a 100 A panel?
Yes. Many installations have breaker totals higher that the main breaker of the panel. It is worked on a percentage basis. Not all of the breakers will be on at the same time. In a home, on a 100 amp panel the average load is 50 - 60 amps. The 100 amp main breaker is protecting the 100 amp rated panel board. If the load current goes higher that the panel board is rated at, the main breaker will trip to protect the board.
Where do you ground on 100 amp panel?
A typical panel has three large wires entering the main panel from the electric meter and a bare ground wire. Two of the large wires are hot and go to the busses where the breakers are mounted. The third wire is common and is connected to one or more common bus locations. It will usually be silver in color with a screw on top to connect white wires from branch circuits. The ground is the metal of the panel itself and there will be one or more ground busses usually copper colored that are connected to the metal of the panel by screws there by "bonding" these ground busses to the metal of the panel. You should also see a copper wire coming from a ground rod connected to the metal of the panel. At the main panel you need to bond the common to the ground. There is usually a screw that allows this bonding to occur. If you have subpanels ground and common are NOT connected at the subpanels.
How should the feeder wires to a subpanel from the main panel ideally be protected?
Sub panel feeder wires are run just the same as any of the circuit wiring in the house. The sub panel is just another load circuit. Make sure that the correct wire sizing is done to feed the sub panel. It can be run behind wall board. If run on the bottom of the floor joists it is best to nail a board to the underside of the joists and then staple or strap the cable to it. If it is below the five foot level from floor grade and on the surface it must be mechanically protected until it rises above the five foot level.
What is MDB and SMDB in electrical?
MDB= Main Distribution Board, it is usually fed from a substation and supplies electricity to a Sub Main Distribution Board ( SMDB ) The SMDB goes on to supply electricity for a panel
Does the common and ground wires hookup together on main box?
Yes, just at the main panel and not subpanels. The bonding of ground to neutral may be a screw or strap.
