How do you check continuity of 300 meter long cable?
Method #1:Bring the ends together. Use ohm-meter to measure resistance between the ends.Compare with manufacturer's specification for the cable's resistance per 100-ftor 100-m.Method #2: Only possible if the cable has more than 1 conductor.At one end of the cable, connect two conductors together. At the other end, use anohm-meter to measure the resistance between the same two conductors. If the metershows open-circuit, then at least one of those conductors is broken in the cable.
What is the allowable propagation delay for a 100 meter Category 5 cable at 10 MHz?
200ns
What is the ampere capacity of 16 square mm cable?
64 amps in less than 100 meter long
If you change out a 60amp meter with a new 100amp meter would the wiring still be big enought to carry the 100amp?
No, on a service change all the wires have to be able to carry the current of the highest rated device. There are tow cables associated with your question. The one from the pole to the meter and the one from the meter to the main electric panel. The one to the meter is the responsibility of the power company and may well be large enough. Since it is in free air its current carrying capacity is not de-rated in the same way as the cable from the meter to your main panel. Since you will have to likely upgrade your main panel it is a good idea to replace the service entry cable to 100 A rating.
If you are in a business and the meter you paying for is also the owner meter how do you get your own meter?
Could be tricky. The business owner WILL need to give their written consent (since it's their building). However - you could contact the energy supplier and ask them for a separate meter. Assuming you rent a room(s) within the main building, the power company should be able to run a spur off the main supply cable for the building to provide your workspace with a separate meter.
