SUMMARY

The discussion centers on the recurring issue of blown fuses in residential electrical systems, specifically with a 20 amp fuse. It is established that using appliances in parallel does not inherently increase the current draw, but the cumulative current from multiple devices can exceed the fuse rating, leading to failures. Participants emphasize the importance of checking the current draw of appliances and suggest that if fuses blow without any devices connected, a fault may exist that requires professional attention. Additionally, the method by which power companies measure electricity usage through power meters is clarified.

The fuse in my House continues to blow. The fuse rating is 20 amps. I can easily make the fuse so that it can't blow out but I know that might heat the wires in the wall if I draw too much current, and can cause an electrical fire. I am wondering, If I get a high grade durable power strip(er)(nah! JK) and put my appliances in parallel will that help the fuse problem.

I am also wondering how power companies know how much power you use, and If I put appliances in parallel will they draw more current?

Your fuse is blowing because you are taking too much current through it.

You could check how much current different appliances draw. Look for a tag on the appliance that gives the power they use. Divide this by your supply voltage (120 volts if you are in the US) and this will give you the current.

These currents add up and if they are on the same circuit they may blow a fuse.

You always use appliances in parallel, even if they come from a power board.

If you are blowing fuses without anything plugged in, you may have a fault somewhere and need to get an electrician to fix it for you.

Your house would have a power meter and this is read at regular intervals by someone from the power company. They subtract the previous reading from the new one to work out how much power you have used. Then they send you a request that you pay them money or else they will disconnect your electricity supply and sue you for the money.
