Not exactly sure what your question is and you need to make sure you are in compliance with electrical code for your jurisdiction. But, generally speaking you install a large breaker (let's say 100A 2 pole breaker to power the sub panel) just as you would install any other breaker in the presently used (hot) panel, and the proper sized cable then goes from old to new and terminates on the main lugs of the new panel. Ground and neutral are usually isolated from each other in the sub panel but depends on other factors as to location of the sub panel, etc.

Can you use a main lug panel for your home or do you have to use a panel with a main breaker?
The service distribution needs to have a disconnect from the utility supply. Most homes use a combination distribution panel. If the home owner wants to have a load center installed then there has to be a fused disconnect ahead of the panel. The less costly of the two options is the combination panel. Labour costs drive the load center, main service switch option much higher because there are more materials to assemble.
How do you install 220 receptacle with white black and bare wires?
Assuming the wires are the correct gauge for application and breaker you use black and white wires as hot. Put red electrical tape on each end of white wire and connect red and black to the breaker output and bare wire to ground lug in panel. At receptacle connect black and red to hot contacts and bare wire to ground lug.
How do you connect 240V electric water heater?
On a 120/240 volt distribution system the ground wire is terminated at the point where the service neutral terminated in the distribution panel. It is usually a double lug the neutral wire connecting into one hole and the ground wire connecting into the other hole. Through this lug assembly there is a machine screw that is inserted through the lug assembly and it screws into the metallic enclosure of the distribution panel. This action bonds the metal enclosure, neutral wire and ground wire bringing the point to a common potential of zero.
Why is the neutral point grounded on a transformer?
The secondary side (output) of a three phase transformer develops a "separately derived system". That is why you do notsupply a neutral to a three phase transformer. It develops its own reference to ground by being bonded to the transformer casing and to a substantial earth ground, such as a ground rod. The XO tap on a transformer provides the neutral to the secondary line. It will have a double wire lug. The neutral wire going to the panel being supplied goes under one lug and the same size wire is to go to the ground lug on the transformer chassis The ground lug is also a double with the other lug to be wired to the earth ground.
CAN YOU CUT A 2 HOLE LUG DOWN TO 1 HOLE?
You can, but you will destroy the lugs certification if you do. Without the certification on a field modified piece of equipment you stand the chance of getting a rejection if the project is ever inspected by an electrical inspector.Just use the double barrel lug until you can get a proper single barrel lug and then change it out. Keep in mind the cost of a double barrel lug is about four times that of a single barrelled lug.
Can you connect Two wires to one main lug in a panel board?
No, you should not connect two wires to one lug in a panel board. Each lug is designed to accommodate only one wire in order to ensure proper connections and to prevent overheating. If you need to connect multiple wires, you should use a wire nut or a junction box to splice the wires together before connecting to the lug.
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.
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.
What methods are used to connect electrical equipment?
The main type of connection to equipment is with an electrical lug. It is about a 50 - 50 split as to whether the manufacturer supplies the connection lug or the customer has to supply the lug.
Can you connect two wires to one main lug in a panel board that is only rated for one wire?
No, you should not connect two wires to one lug that is only rated for one. This can lead to overheating and potentially cause a fire hazard. It is important to follow the manufacturer's guidelines for wire connection to ensure safety and proper functioning.
What is the answer to in a typical home electrical panel installation the ground wire is connected directly from a geound rod driven into the ground to the?
Connect other end to the ground lug in the service entrance part of your panel.

How do you install 220 receptacle with white black and bare wires?
Assuming the wires are the correct gauge for application and breaker you use black and white wires as hot. Put red electrical tape on each end of white wire and connect red and black to the breaker output and bare wire to ground lug in panel. At receptacle connect black and red to hot contacts and bare wire to ground lug.
Do you need a main dissconnect for a 400 amp 3 phase service?
Yes, a main disconnect is required for a 400 amp 3 phase service to disconnect power from the building. It is a safety feature that allows for easy shutdown of the electrical supply during maintenance or emergencies.
Where is the lug wrench on a 1999 Ford Explorer?
At the rear of the vehicle, in the cargo compartment, there should be a panel on the left side. Remove that, and the jack and lug wrench will be in there.
In a typical home electrical panel installation the main ground wire is connected directly from a ground rod driven into ground to the 1 case of the panel or 2 main breaker switch or 3 l?
The main ground wire in a typical home electrical panel installation is usually connected directly from a ground rod driven into the ground to the case of the panel. This helps to ensure that the panel is properly grounded to prevent electrical shocks and provide a safe path for electricity to follow in case of a fault.
Where is lug key located in 1999 mercury mountaineer?
I believe it should be attached to the lug wrench that is stored in behind the removable plastic panel in the cargo area on the drivers side
