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.

We can calculate the power released in a bulb by multiplying the voltage in Volts across the bulb by the current in Amps flowing through the bulb (W = V x I). For example a current of 2 Amps flowing through a bulb with 12 Volts across it generates 24 watts of power. In the UK, domestic power is supplied at 240 Volts. A 100 Watt bulb will therefore draw a current of 100/240 Amps (about 0.4A). This means a 1A fuse can be safely added to the mains plug of a desk lamp with a 100W bulb because 1A is much greater than 0.4A. In the USA, the domestic supply is typically 110V, safer than the UK, and this means a 100W bulb draws a current of 100/110 Amps (about 0.9A).
