How Long Does It Take To Check Continuity In A Long Wire (And Why)?

Exact Answer: 5 Minutes

Even after setting up everything one needs to have the right electrical connection, it is necessary to check them often. The continuity is important for the electricity to keep passing through the house, and every time there is a fluctuation in the electricity, one should not try to reach the electrician to fix up even the most common electrical issues. It is necessary to know the tiniest things about electrical connections so that one can fix them up all by themselves without asking other people’s help.

After installing the wire connections, the electrician always makes sure the continuity is maintained. Continuous wires make sure the function of the circuit and non-continuous wires result in the non-functioning circuit. It can also lead to problems like power outages and some other problems in the grid. It is easy to check the continuity of the short wires while checking the long wires can be a while.

Normally, people use a multimeter to check the continuity in a long wire and the process takes about just 5 minutes to set up the multimeter and check the continuity.

Whenever there is some trouble with the wire, first the continuity of the wire must be thoroughly checked. First, to check the continuity of the wire, certain steps and precautions must be followed. Both the ends of the long wire must be disconnected before testing them. The wire must not touch anything to get a good reading. After that, a multimeter must be set. Before checking the wire, the power supply to the wire must be cut off. Checking the continuity of a long wire can be done by just an individual.

The multimeter must be set to continuity and one lead should be put to the ground. Another end should be put to the wire that one is checking and working on. The tester will display OL. There shouldn’t be a path to the ground, and if there is, the wire is damaged. One end of the wire must be grounded. Normally, there is a spare ground terminal on the DIN rail. This can be used to terminate the wire. The end of the wire which isn’t grounded must be checked for continuity to ground.

After the other end of the wire is grounded, the continuity to the ground must be read. The integrity of the conductor can be proved by grounding one end of the wire and meter continuity. When there is a break in the wire, the continuity cannot be read from the ground to the opposite end.

Why Does It Take That Long To Check Continuity In A Long Wire?

To check the continuity of the long wire, one must understand the basics, know about the continuity test, prepare the multimeter, and carry out the test. A multimeter can be used to test current, resistance, the voltage in switches, circuits, connections, any electrical components, appliances, and any type of conduct. To test the continuity, the multimeter must be dialed to ohm settings. The multimeter will now display 1 or OL, which means open loop. OL is the highest scale of measurement. \

At this point, the multimeter measures the resistance between the two leads connected to the wires, where the resistance is normally more than it can be counted. The multimeter must be set to 200 ohms since it is appropriate for long wires. When one wants to test the components for low resistance using the multimeter, the ranges must be below, and if the components are tested for high resistance, higher ranges must be set.


A simple summary of the process is that first the electricity supply must be cut off. After that, the multimeter must be set to measure ohms and the range must be set. After that, the multimeter probes must be connected to the ends of the wire and finally, the reading must be checked.

The entire process will normally take about 7 to 8 minutes if it is being done for the first time by the person. When the person has had practice, the process will just take about a maximum of five minutes.
