No, your live (brown) cable takes the load and pulls the amps from the supply, not the neutral. Your ammeter should be clipped on the live to get a correct reading.
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.
On a 200 amp or any size service the ground wire is easily identified. Look in the distribution panel for the neutral bus bar. This is where the service neutral (white wire) is connected to the distribution panel. There you will see a bare copper wire connected to the same neutral bar. This is the ground wire that is connected to the ground rods out side of the house.
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.
The NEMA 6-20R is a 2 pole 3 wire grounding receptacle that is rated for 250 volts. It is not meant to have a neutral wire connected to it. The receptacle is designed to have 240 volts connected to it.
Ground wire can be appropriately bonded to the neutral and cabinet at the service box by connecting the neutral and ground wires from the feeder wires to the neutral bus bar and the ground terminal located on the same cabinet at the service box. White wire (neutral) must be connected to bus bar and bare wire must be connected to ground terminal in the same cabinet.
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.
The neutral wire and power wire are never connected together.
Because the white wire on a 120 volt circuit is the neutral wire that is connected to the silver screw on outlets and switches. It is connected to the neutral bar in the service panel.
An ammeter is always connected in series in the circuit.

The voltmeter is connected across the supply and the ammeter is connected in series with the supply.
The positive terminal of the battery would be connected to the positive terminal of the ammeter. The load would then be connected between the two negative terminals, positive side of the load being connected to the negative side of the ammeter.
The NEMA 6-20R is a 2 pole 3 wire grounding receptacle that is rated for 250 volts. It is not meant to have a neutral wire connected to it. The receptacle is designed to have 240 volts connected to it.
Ammeter is coneccted in series with circuit but Voltmeter is connected in parallel.
In most electrical devices the neutral wire is connected under the silver coloured screw.
Series connect it within the line of the circuit for which you are interested in measuring the current flow.More detailSince we measure the flow of current IN the circuit, the ammeter must be connected in series with the part of the circuit for which you are interested in measuring the current flow.One of the ammeter's terminals must be connected to a point of the incoming current flow and its second terminal must be connected to the point of on-going current flow. To do this, cut the relevant circuit wire and connect one terminal of the ammeter to each end of the cut.
