Bulb trick replacing fuse ?

[bianchi77]

Guys,

Is it safe if I change the fuse temporarily with bulb to see a short circuit in a high side of power supply ?

Will the bulb blow ? or it's just glowing replacing a fuse ?
Will I burn something else and make it worse ? Or the energy ( high current) has been passed to the bulb and will not damage anything else

Thanks

The bulb will limit the current. It will only allow the power (watts) at which it is rated through, thus It will prevent fuse (or other components) from blowing.

for example the device I want to test is 24VA....it's ok if I use a 60W bulb ?
so the bulb power must be higher than the device I want to test ?

if there's short, the bulb will be on brightly, if not....it's not on or dimming ...?

dont know about the whattage, but the rest is correct.

i find that if the wattage is to low for the device to run, it's still o.k. for testing if something is shorted.

the bulb is not blowing if there is short, isn't it ?

if there is a short the bulb will go bright.
just as long as the voltage is not higher than the bulb rating.

You mean...the input voltage?240v and it will protect the circuit into further faulty?

24VA...Is that correct??...If you are working with 220V then you will be using 0.11 Amps??
