If the exact gas demand value is not shown, the next larger value in the same row (to the right) should be chosen. Above this demand value (at the top of the table) is the correct size of tube to be used in supplying this capacity. This method should be used to size each outlet and section of piping.

'Universal Voltage' That input of 120/240v means there's a switch inside the device so you can run it on 120v in one position, in the other position it'll run on 240v.RedNek Â· 4 years ago.

So volts is a measure of the strength of an electrical source at a given current or amperage level. If we bring 100A into a building at 240V, we have twice as much power available as if we bring in 100A at 120V. Volts (continuing the same water analogy) is the pressure in an individual electrical conductor.hen a homeowner or client asks you how much electrical service is provided s/he needs to know the service ampacity and voltage. In the US and Canada service voltages are commonly (nominally, that is, not exactly) 240 volts at the electrical panel, a system which supports both 120V and 240V circuits in the building.
