my fuse in the kitchen blew out. I have the old screw in type fuses. the one that blew out controls my fridge. It has a copper type sleeve on the end similar to a lightbulb and on the face it says 25T. But when i went to the store they only have a 20TL or a 30TL with the same copper sleeve. In my fusebox next to the fuse that blew out is also another 25T that controls from what i could figure out my front porch light, indoor wall outlit which has a lamp on it and the clock radio in my bedroom. I dont know wether to use the 20 or the 30? Would the 30 be too much amps and cause my house to catch fire or should I use the 20. I was so confused I bought both kinds and right now i am using the 20. so far so good. Also on the back of the box of fuses it says do not put more watage than is allowed in the socket or it can cause a house fire. But the front of the fuse says amps not wattage. Are they the same or different. I am so confused. Help me please.|||Always better to go with the lower amp rating when replacing fuses if they don%26#039;t have exact size of the old blown fuse. Now days 25 amps is sort of an odd size and the old type screw in fuse boxes are hardly used anymore, that is maybe why they didn%26#039;t have a 25. You can always take the 30 back for refund, or keep it to replace a 30 that blows-if you have an existing 30. Amps(current) are the intensity of the flow of the electrons being pullled through the wire to whatever device is using the electricity. Wattage is the power being used by the same device. Usually when you have to replace an electrical item it will have several different ratings such as an amp rating a voltage rating and a watt rating-that,of course, is what they have been tested up to and not to exceed.
Hope this answer help to alleviate the confusion.|||Never use a fuse thats rated higher then the one you replace or what is indicated on the panel. You can use the 20amp temporarily in the non critical fuse location and use the 25 amp in the kitchen circuit.
Then when you can replace the 20 with one of the same rating.
The 20t ,25t 30t, is just the current rating (amps) you need not try to calculate the wattage.
You may also want to save up your pennies and get your electric sevice and panel upgraded soon. Fuses were good for their time but are not the safest things.|||watts = volts x amps. Thus, a 15 amp circuit (typical in houses ) can carry 15 x 120 = 1,800 watts. On this circuit you could handle say 30 60w bulbs. An electric heater probably draws around 15,00 watts by itself.
Based on what you said, use the 20-amp fuse. This such be sufficient since higher capacity circuits are typically used for special applications like electric dryers.|||you can try this site: http://www.fuseone.com/|||old screw in type fuses are illegal
