 Bob things are a little different in Mexico what you are saying is correct but Mexico unless the have changed uses no grounding plugs like we have here only the 2 prongs most places there you really have to watch 30 and 50 amps plugs no telling what you will get lol most of the time it will be 220v

good luck
Life is short drink the good wine first

Steve. When you travel in Us there will be A green Earth Ground. A old trick before this was adapted here in the 1960's when we approached a metal bldg or bus we touched it first with the back of our fingers during wet weather.  If it had a electrical charge your hand will contract and push away.  If you grip it with your palm it will contract and you can't let go.  Be safe and live long.   Bob   Only did hand thing if had doubts had a couple times I didn't that I wish I had.

[He said he never heard of "neutral" and "ground" being two separate circuits. And he does huge factory installations.

So what does Neutral connect to and what does Ground connect to?

  The two main plugs in a standard houshold electrical outlet signify the hot and neutral. You have to have both to run anything. In the US the voltage between those two is 120 volts, what Mexico has I dont know. In the US we have outlets with three terminals. The two slots plus a round terminal below them. The round one is a ground wire. If your power saw shorts out, rather than electrocute you the energy will go into the ground wire.

  As an example, in my yard I have power strung up here on power poles. The last pole has a meter and main power disconnect. All power comes from that panel into the house panel. Power at the pole is 7240 volts IIRC. There are two wires, one hot, one neutral. The neutral is connected to a copper wire stapled into the pole that is connected to an 8 foot copper ground rod driven into the ground. The hot and neutral both goes into the transformer that drops the voltage to 120 volts on two wires called legs, and three wire come out, two 120 volt hots, and the neutral. They come into the disconnect, the two hots connect to the two side of the main breaker. The neutral goes to a "bus" bar. The ground comes into the box and goes to a seperate Bus. I have four wires going into the house panel. Two connect to the main breaker at the pole, one connects to the neutral Bus, the other connects to the ground Bus. In the house panel, all neutrals go to the neautral Bus, and all grounds go to the neutral Bus. Therefore, all grounds at the outlets in the house are grounded back to the pole. All neutrals are isolated from ground "except" at the pole. Often there are additionalground rods at each breaker/fuse panel, and also ground wires connected to water lines.

  In an Bus with a generator, you have the same deal, but the Bus isnt grounded to earth, its isolated from the ground. All grounds go to the chassis ground, all neutrals go back to the generator along with the hot (s). The ground and neutral are connected together "bonded) at the generator, just like at your main disconnect in your house.
 
  There is a problem connecting the Bus generator to your house system, because of the bonded neutral at the generator. With your Bus NOT grounded to earth, you could get killed if you touch the Bus under the right conditions. Its rare, but it can and has happened.
