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.

At 100 V ac it would try and draw a current of nearly an amp if it were able. The point is that it will try and draw more current at a lower AC voltage and this could blow an internal fuse or damage the switching transistor-the average current may only be 1 amp but the switching current might be 10 amps.onsider an appliance only intended for operation on 240V AC but is able to work from (say) 200V to 250V. To do so might mean it uses a switch-mode power supply to regulate the internal DC voltages. Let's say it required 100 watts internally, maybe some form of audio amplifier.
