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?

Two wires can be connected to one main lug in a panel board if the lug is designed to hold two wires. The data will be written on 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.

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?

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.

Do you need a main dissconnect for a 400 amp 3 phase service?

No, you can use the six main rule. This means you would have a 400 amp main lug panel, with six breakers or less, but no more than six. You can also use six individual disconnects.

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.
