What size wire cable and fuse for a 9.8KW shower?
7.2kW shower = 32 Amp fuse = 6 mm2 cable size7.5kW shower = 40 Amp fuse = 10 mm2 cable size8.5kW shower = 40 Amp fuse = 10 mm2 cable size9.5kW shower = 40/45 Amp fuse = 10 mm2 cable size10.5kW shower = 45 Amp fuse = 16mm2 cable size
How is low voltage circuit normally protected?
If it is then it has a 3 or 5 amp fuse. Some are not.
If a 240V circuit is protected by a 15A simi-enclosed fused and has an electrical earth-fault loop impedance of 1.9 ohms determine the earth fault current in the event of a zero impedance earth fault?
I am assuming that its a 240 Volt AC circuit supplying an inductive load with a fault loop impedance of 1.9 ohms at the time of the short circuit. The power factor is assumed to be 0.8 The instantaneous earth fault current value would be; Current = (Voltage x Power Factor) / Impedance (240 x 0.8) / 1.9 192 / 1.9 = 101 Amps. However this may be a trick question as it doesn't ask for an instantaneous value, the fuse will limit the fault current to 15 amps and should disconnect the circuit within 0.4 seconds.
Why does the primary side of a step down transformer burn out and not the secondary of a 480V to 240V transformer?
Sounds like the wrong size fuse protection was used. The transformer should be protected to its kva capacity.
How are fuses or circuit breakers connected with other elements in the circuit?
Fuses are normally associated in series with the component(s) to be protected from over-current, so that when the fuse blows (opens) it's going to open the whole circuit and prevent cutting-edge through the ingredient

What is the correct fuse for a 7.5 kilowatt electric shower?
To answer this question the voltage of the shower is needed.
Does a cigarette lighter work on a fuse?
no it doesn't The circuit is protected by a fuse.
What sort of fuse would you select for an installation that required high current interrupting ability and an allowance for instantaneous over currents?
The best type fuse for an installation that required high current interrupting ability and an allowance for instantaneous over currents, would be the largest fuse sufficient for normal use and a relay to another fuse for the over currents. It is always best to consult an electrician.
How is the circuit protected?
By a fuse or a circuit breaker.
Where is the cigaratte lighter fuse located in 1990 buick century?
If you do not see a fuse marked lighter, it may be protected by the fuse for the radio.
License plate fuse?
The license plate light circuit is protected with the tail light circuit fuse.
Are the electrical gauges in a peterbilt 379 circuited through a fuse?
Yes, all circuits are protected by a fuse.
What fuse controls the O2sensor heating?
sensors are not protected by fuses.
Is there a fuse for the cigarette lighter on a 2003 Toyota Echo?
Yes, all cigarette lighters are protected by a fuse. It may be using the radio fuse.
Are car computers fuse protected?
Yes all cars do this. Look for fuse lankest PCM, ECM,BCM,OR ECU
The main reason the minimum overload protection to an instantaneous shower has to be between 30 to 40 amps is why?
In a 230 volt system such as in the UK and Europe, the average shower takes 35 to 40 amps. The protection should match the highest load anticipated. edited by another person: I have this same question on my plumbing course and i believe i can help you. I have put KW rating as i believe its connected to a previous question, what is the fuse rating of a 9KW shower. well 9000W divided by 230V = 39 amps, so a 40 or 45 amp fuse would be considered. and then going back to this question, why is overload protection required to be between 30 and 40, because of its KW rating. Would that help you?
