What's the deal with blowing fuses at home?
In general, there are the following cases, which can blow the fuse.
①, line parallel.
②, short circuit of the line
③, overloaded use, use of electrical appliances beyond the rated current of the fuse blowing.
④, wrong installation of the gate, connecting the gate without connecting the wire tightly, the fuse crimped tightly, in the use of the joints easily caused by high temperature heating, so it is also easy to burn the fuse.
The second question is, how to measure current with a multimeter?
When using a multimeter to measure the current, and speaking of the multimeter range switch, adjusted to the AC voltage and current block, you can first estimate the total load of all electrical appliances in the home is how much, will be adjusted to the multimeter ≥ the total load current of the home electricity connected in series on the line can be measured (pay attention to the safety of operation, to prevent electrocution, do not recommend that the non-professionals, the operation)
As the current block of the multimeter, the range is small, it is recommended to use a special instrument with a larger range, clamp ammeter, as long as the single-phase wires to be measured by laying the shape, placed in the clamp meter (note that the range switch of the clamp meter will be converted to the sweet Zin table of the current file on the appropriate gear), this is the number of figures displayed, that is, at this moment, the current of the electricity (A)
