250v fuse how many amps?
482704
Fuses are rated in amps. Most fuses for household items are 250V. We are told that we can use 250V fuses of the same amperage rating for our nominal 120V circuits. Thus, if I need a 5 amp fuse for an amplifier I get a 250V 5 amp fuse.

25-amp 120-volt circuit: 25 amps x 120 volts = 3,000 watts. 20-amp 240-volt circuit: 20 amps x 240 volts = 4,800 watts. 25-amp 240-volt circuit: 25 amps x 240 volts = 6,000 watts.

Amps = Watts / Volts 4160 Watts / 208 Volts = 20 Amps. 3600 Watts / 240 Volts = 15 Amps.

The fuses and relays are often identified inside the power center cover. If you are replacing a blown fuse, replace it with a fuse that has the SAME amp rating as the original.

40-amp 240-volt circuit: 40 amps x 240 volts = 9,600 watts. 50-amp 240-volt circuit: 50 amps x 240 volts = 12,000 watts.

['I(A) = P(W) / (√3 × PF × VL-L(V) ) So amps are equal to watts divided by square root of 3 times power factor times volts.', 'amps = watts / (√3 × PF × volts) or.', 'A = W / (√3 × PF × V) Example. ... ', 'I = 330W / (√3 × 0.8 × 110V) = 2.165A. Amps calculation with line to neutral voltage.']

There are some special fused sockets that DO have fuses but they look different to an ordinary 13amp socket. They will have a rectangular cover in the socket faceplate which holds the fuse inside the socket and as a notch at one end. You get at the fuse by levering it out (carefully!) with a screwdriver in that notch.

A 12 gauge wire is rated for 25 amps. NEC only allows for it to be protected at a max of 20 amps (unless following an exception for motor loads).

Many fuse covers contain extra car fuses and fuse pullers on the back side. If you use one of them, replace it the next time you go to the auto parts store. Vehicles today have 40 or more auto fuses grouped in two or more places and usually vary from 10 to 30 amps.

['A 500 kVA transformer will draw at full load nearly 700 Amps per Phase at 400 Volts. The primary current at 11 kV is 52.5 Amps / Phase.', 'To allow for overload a factor 1.6 has to be taken into account.', 'The VCB has to be rated for 100 Amps/11 kV minimum.', 'An electrical engineer will do the exact calculations for you.']

Amps = Watts / Volts 3600 Watts / 240 Volts = 15 Amps.

Each socket (presumably for flat pin plugs) is designed to deliver a maximum of 13 amps - hence the 13 amp fuse you find in new plugs. Thus a double socket can supply no more than 26 amps.

Replacing a Circuit Breaker Switch or Fuse Standard, 15- to 20-amp circuit breaker switches cost $5 to $10 each. Standard, 15- to 20-amp fuses come in packs of three costing $5 to $10. Homeowners should expect to pay at least $100 for professional installation.

A 4500 watt element draws 18.75 amps at 240 volts. Code requires wire sized at 125% of continuous load. 18.75 x 1.25= 23.5 Amps.

For a maximum of 50 amps, you'll need a wire gauge of 6. Fifty amp breakers are most often used to power many different appliances.
