A megger is a testing device used to test the insulation integrity of conductors. It measures resistance. It is terribly imprecise so actual readings are difficult to determine. Any passable reading will approach infinity (meaning almost infinite resistance) since there should be no flow of electricity from one conductor to another or from one conductor to ground.
When you talk of the capacity of a service you are talking about the capacity of the equipment to handle a certain amperage. A 400 amp service has to have all of its equipment to be rated to handle 400 amps. The maximum capacity of the service will be what the service is protected at, be it with fused or breakers. If the fuses of the main breaker were 300 amp rated then the maximum capacity of the service would be 300 amp even though the equipment is rated at 400 amps. The service capacity is governed by the fusing that is protecting the service.
reading rate is the amount or how fast u r reading......... as in its timing u.....that's all i can tell u pplz.....Reading rate is based on texts of increasing difficulty. Rates of reading include reading for memorization (less than 100 words per minute), reading for learning (100-200 wpm), comprehension (200-400 wpm), and skimming (400-700 wpm).
Normal home electrical service in most residential areas is provided at 120/240 volts. A 400 amp service would still typically be delivered at this voltage. The 400 amp rating indicates the maximum current capacity that the service can handle.

In a 400 amp service wire size chart, you can find information on the recommended wire sizes for conducting electricity in a system with a 400 amp capacity. This chart will provide details on the appropriate wire gauge, material, and insulation type needed to safely and efficiently handle the electrical load in a 400 amp service setup.
i need to buy a service manual for a 1982 yamaha maxim 400
4 inch rigid conduit
20 ! reading from left to right - all the multiplication totals to 400. 400/20 is 20.
The service manual for this vehicle can be found in an automotive store. It can be obtained from the dealership or from the manufacturer.
