An electric geyser has ratings 2000W 220V marked on it . what should be the minimum rating, in whole number of afuse wire that may be required for safe use with this geyser?
please answer the question as soon as possible
2000/220 = 9 amps.
But if the line voltage varies up to 230 or 240 volts, that will go up to nearly 10 amps.
Now, a 10 amp fuse will not help.
Its better to use a 15 amp fuse, and use wire that is rated at that current.
Hope this helps.
