i'm supposed to put fuses as system protection for my 4.5KW heating elements @230Vac. i had it connected at star (3 heating elements each heaters) and i have 3 heaters.i rated my fuse at 25Amp.do you think that ampere is enough?
thanks!
thanks!
How many amps? Amperage is not the only rating to consider.i'm supposed to put fuses as system protection for my 4.5KW heating elements @230Vac. i had it connected at star (3 heating elements each heaters) and i have 3 heaters.i rated my fuse at 25Amp.do you think that ampere is enough?

Were they at room temperature when you measured them? Resistance varies with temperature. If you know the material they are made from, you can look up the temperature coefficient of resistivity and estimate the resistance at working temperature.My conflict now is when I did an actual measurement of each heating elements resistance I got 34ohms each? How can I possibly arrive to a 4.5KW heating element?
