Should the neutral in a service panel be connected to a system ground electrode?

No, the neutral (white wire) should be connected to the center tap of the supply transformer.
The electrical service that comes to your home should have 3 wires. Across the 2 black wires should be 240 VAC. That comes from a transformer that steps down from the transmission voltage that is on the high voltage lines.
The "center tap" of the output of that transformer gives you 2 legs of the supply, each at 120 VAC.
In years past, the center tap has often been connected to ground, but that is no longer the case.
The center tap is the neutral connection, and the ground is the part that keeps you from being electrocuted.

Should neutral wire of lamp be connected to the 3amp or the 6 amp side of a canopy switch?
You should never switch the neutral wire. The neutral of the appliance should be connected directly to the neutral wire leading to the service panel neutral bar.
Downstream of the electrical service box the neatral and gound wire should be separted?
Plain and simple.... The Neutral and Ground should ONLY be connected together inside the Main Service Box.
What should the clearance be from service entrance panel to grounding material?
grounding material is not a good word but as short as possible is a good answer the entrance panel must be connected to the best possible ground this is called the grounding electrode the grounding electrode conductor connects to the ground bar in the entrance panel if the panel has a a neutral the neutral bar can be bonded to the ground bar Grounding electrodes form best to worse well casing water pipe (NOT plastic) buried plates or wire grid or bonded reinforcing steel driven rod if you are talking about distances to the panel it should be centered about shoulder height doors need to have about 2' of clearance in all directions weather open or shut
Can the bare grounded neutral conductor of a service be buried directly in the ground?
A bare grounded neutral should never get close to the ground if it is wired properly. When the neutral leaves the meter base it is in conduit and should enter into the distribution panel where it connects to the neutral buss. It is at this junction that the copper ground wire is connected after coming from the outside ground rod or ground plate which ever grounding system was used.
Does the neutral wire go on the silver screw when wiring switches or outlets?
No, the switch just breaks the hot side of the circuit. The incoming hot wire should be connected to the top screw and the load side of the switch should be connected to the bottom screw. The neutral wire is usually connected together with a wire nut and pushed to the back of the switch box.
What is an electrode conductor?
It is the conductor that is used in service distribution panels that bonds the distribution panel's neutral bus bar to the ground electrode (rod). This brings all of the distribution panel neutrals that are connected to the same supply system to the same potential, that being zero. Should a supply service neutral open this ground wire will maintain the systems integrity until repairs can be made.

Can you crimp copper grounding electrode to aluminum neutral of service entrance?
You should not have to crimp the copper grounding electrical wire to the aluminium service neutral. There is only one place where these two wires should meet. In the service distribution panel there is a neutral block where the two wires are connected. There are individual terminal points in the block. Tighten the ground rod wire under one of these points and place the incoming service neutral under another point in the same block. In this same block there will be a machine screw that bonds the neutral block to the distribution panel's enclosure.

What besides the neutral system should be bonded to the ground?
Answer for USA, Canada and countries running a 60 Hertz supply service.Nothing but the neutral bus should be bonded to the ground electrode.
What is color code for neutral earth pit?
You can not have a "neutral earth" the "neutral" and the "earth" are separate wires/connections and should not be cross connected or muddled up.

Where on a Mazda auto 1994 is the park and neutral switch?
if you look on the transmission, you should see two wires connected to the neutral switch.
Why black wire and white wire both have power?
In the US, house wire has the BLACK wire connected to the HOT phase of the service input. The WHITE wire is connected to the NEUTRAL of the service input. Normally, both BLACK and WHITE wires are each connected to the 2 LOAD terminals. It is also normal that the WHITE service wire is connected to the wider spade outlet receptacle. The BLACK wire would then be connected to the shorter or narrower outlet spade receptacle. In wired screw lamp circuits, it is normal to wire the BLACK service wire to the center pad of the lamp socket and the WHITE wire to the screw shell of the socket. In switch circuits, it is normal to wire the BLACK service wire to the switch. The HOT service circuit is then opened or closed by the switch. Measuring voltage on your neutral means there is a break in neutral. If the neutral is broken you will measure voltage across the break or from the break to ground. Under this scenario you will measure the same voltage as you do on your hot wire and your load should not be working. Measuring voltage on your neutral less than on your hot wire may mean you have a problem where your neutral is supposed to be bonded to ground in your main service panel. In this scenario your load may be working but you need to check the bonding connection.

All three legs of my dimmer are hot?
If the hot is connected to the supply and it is turned on and the switch is turned on and the neutral not connected this could be quite true. Connect the neutral to the supply neutral and shut the switch off. Now the only reading that you should get is the hot supply.
