I am adding a 30 amp sub panel - the problem I have is the neutral bus is full what are my options?
Best answer - If panel can accept, add an additional bus on the other side and bond the two together.
Least desirable answer - split bolt the neutral to one of the existing. Under no circumstances should you place multiple wires under one terminal.

The neutral wire for the sub panel will only be a #10 conductor. Neutral wires can be doubled up under a single screw in the neutral bus. Turn the main breaker off to do this installation. Double up two #14 neutrals to make room for the #10 neutral wire. There is no code rule as to how many wires can be installed under a terminal on the neutral bus. There is a code rule though about not doubling up circuit feeders under one breaker terminal.

What is neutral grounding resistor panel?
A neutral grounding resistor panel is used to resist fault current to the ground. It is used for alternator protection protection purposes. When a fault occurs in the alternator, the panel helps force the current to the ground.
Does a 480 volt panel have a neutral bus?
Usually yes. A typical 480 volt panel is a 3 phase panel with 480 volts line-to-line and 277 volts line-to-neutral. However, I did once see a panel that was 480 volts, 3 phase, but because it served only motors it did not have a neutral. (a 3 phase motor doesn't use a neutral.) Similarly, if a panel uses only 2 legs of a 3 phase 480 volt system, which would be called single phase, it would not require a neutral if it only feeds 480 volt single phase loads. But I find the idea of no neutral to be extremely unusual and in my one personal experience, I blamed it on the age of the system. In 16 years of commercial and industrial construction I have never installed a 3 phase panel without a neutral and all my work is designed by engineers.
How and where do you connect the white wire from the shunt breake to the electrical panel?
The white wire would go to the neutral bar. Just be sure of the shunt trip voltage required for the breaker and land the white wire on the appropriate neutral bar in the correct panel.
What size neutral wire for 200 amp service panel?
AWG # 3/0 copper.
When would you want to upgrade the main electrical panel vs just adding a sub-panel?
Depending on how many breakers you have in your exisiting panel if you only have a old 6 or 8 circuit panel then I would suggest a new panel, In the newer building world where you have a 20 or 30 circuit panel then I would suggest a sub panel.
What is the reason when you read voltage between neutral and earth?
It usually means the neutral is broken somewhere between where you are measuring and the panel. If you are measuring this in the panel, it means the panel is not properly bonded and you need to call a competent electrician to fix the problem.
How can you tell if a neutral bar is bonded or not to the panel?
Take a look at the junction where the ground wire and the neutral enter the panel. There you should see a green grounding screw that protruded through the neutral block and into the metal enclosure of the distribution panel.
Where do you hook your neutral in your breaker panel if there is no neutral bar?
Unless the panel is the Main Panel (first panel in the system after the service feed) all panels have a neutral bar. Otherwise you are missing pieces. If this is the Main Panel, the neutral bar is bonded to the ground by a bus-bar. If this is the case, neutrals should all be connected to the same side of these bonded bars. Electrically it makes no difference, however it is a good practice to keep electrical panels neat and organized. If this is not the Main Panel and there is no neutral bar, STOP, PUT DOWN THE TOOLS, CALL A PROFESSIONAL. This panel is missing pieces and may be dangerous. It is possible to have a panel without a neutral. This panel would serve only 240 volt loads where no neutral is needed, however I have not seen this done in residential applications.
Why do you isolate the neutral?
If you are working with a sub panel, there are a few reasons to isolate the neutral. Firstly, currents will then return to the main panel and service ground.
How do you wire floating neutral in sub panel?
You need to be more specific. Is this your feed?? Is this a home run (the wire that is feeding a circuit). Anyway if this is your feed wire (the wire supplying power to your sub panel) then you will land your two hots , then you will land your ground wire on the lug that is bonded to the panel. Sometimes this is a ground bar that can be screwed to the panel itself and then your neutral will go to the bar that is not touching anything. So your neutral coming in will be tightened down to the same bar as the neutrals that are feeding the circuits. This is assuming you'r are feeding your sub panel with 2 hots, a ground and a neutral.
Why Hot and neutral are both hot?
You'll have to explain your problem better.If HOT black and Neutral White in your house wiring are both hot then Neutral is NOT bounded to ground in main panel and neutral could be floating. There should be no voltage between Neutral and Ground (Bare wire in panel). By code if there are multiple panels Ground is only bonded to Neutral in th emain entry panel. I have seen cases where this bonding was not done. At your main panel check voltage between neutral and ground. It should be zero.
Where is the backup light fuse for a 1992 jeep wrangler?
Fuse panel on the drivers kick panel, but your other lights would be out too. What you more likely have there is a reverse/neutral safety switch problem, when out of adjustment the lights will not come on.
What is the difference between a ground bar and a neutral bar in an electrical panel?
A ground bar is used to connect the grounding wires of electrical circuits to the panel's grounding system, while a neutral bar is used to connect the neutral wires of electrical circuits to the panel. The ground bar is for safety, while the neutral bar is for completing the circuit.
Can you tie the neutral wire on a sub feed to another panel to the main neutral lug?
No, the neutral wires from different panels should not be tied together at the main neutral lug. Each panel should have its own separate neutral connection to the main service panel to ensure proper grounding and to prevent potential hazards such as ground faults. Mixing neutral wiring from different panels can cause electrical imbalances and safety issues.
Is neutral connected to earth in main panel?
Answer for USA, Canada and countries running a 60 Hertz supply service.Yes, the neutral is connected to a system ground in the main distribution panel.
What is neutral grounding resistor panel?
A neutral grounding resistor panel is used to resist fault current to the ground. It is used for alternator protection protection purposes. When a fault occurs in the alternator, the panel helps force the current to the ground.
How do you wire a 15 amp 120V breaker in a 240v 30 amp breaker panel?
Look to see if the 30 amp panel is fed with a two wire or a three wire. If it is a two wire then you are out of luck. If the panel is fed with a three wire then the panel should have the neutral terminated in the panel. It is this neutral that you need for 120 volt connections. You didn't state how many panel slots there are in the panel. If you are able install a 15 amp breaker into the panel and connect the wires going to the load. The black wire will go to the breaker and the white wire will go to the neutral bar in the panel.
