Old residential fuse box
1.One fuse blows all the time?
2.You changed the main fuse, or one of the main fuses, and get no results?
Suggest seeking a Professional Electrician Pronto!
Fuses are a Protection device. If a fuse blows there is a problem. If the same fuse consistently blows, there is a Definite problem!
If changing The main cartridge fuse, or one of the main cartridge fuses does not bring about a change,
THERE IS A REAL PROBLEM!!!
Many times I've seen where a house has been added on to, and the electrical system has not been upgraded to match. A fuse panel definitely suggests this. Circuit breaker boxes have been implemented for a long time, and in the US, a 150 amp service panel is the minimum. (2008 NEC Code)
Someone who wasn't a licensed electrician, (Or someone who was a licensed electrician, but who
who should have had their license pulled), has attached wiring where it shouldn't have been.
More than one Load wire going to a protection device, (Be it a fuse, or a circuit breaker), is asking for trouble.
Each circuit should have it's own fuse. Each room should be on one circuit. Lighting should be at least on two circuits. At the Minimum!
(If the fuse blows for a lighting circuit, and there's a storm going on outside, you sure don't want to be hunting around for a flashlight in the dark, when it's easier to find a room that still has lighting. Find the room/s that still have electricity, and flip a switch on)
Kitchens should have many circuits. One for every three receptacles, using a 20 amp breaker. One for a microwave. (20 Amp) One for a garbage disposal. (20 Amp) One for a dishwasher. (20 Amp) One for an electric stove, (If used). (40 Amp) I even like the lighting to be separate. On it's own breaker. There should be a GFCI used, if the receptacle is within 6 inches of a water source. (Ground Fault Circuit Interrupter)
The NEC Code is a MINIMUM. It is implemented to keep people safe.
Your fuse box may have many circuits tied to one fuse. Common practice used in the past, and a Very Unsafe One!
The following is for INFORMATION PURPOSES ONLY!
It is NOT an advisement to repair!
The fuse panel may be under a leaky roof, causing the contacts for the fuses, (Round individual ones, or the main cartridge fuse), to become corroded.
If you have a corroded contact surface, you will have resistance. Resistance causes Heat. Heat causes Fire!
There may be loose wires where they connect to the fuse holders. AC electricity vibrates. Alternating Current. It flows back, and forth on one wire.
If the screws on the fuse holders, have come loose from the vibrating of the AC, there will be resistance.
I've seen where screws have come so loose, that the wire was just about to fall off. The homeowner was lucky I called a professional in.
There is no way I can safely guide you in a solution to fixing your problem, Other than suggesting seeking a professional electrician.
The Main reason I posted this, is to Implore that you get professional help for your problem. You have a very dangerous situation, and I fear for your safety.
I realize a professional electrician is not cheap, and the world is an economic crisis, but we are talking about your life here, or maybe more than one.
