If the electrical contractor has all of the materials ready for the job, the man hours should be about eight hours.
A 350 amp service is not a standard service distribution. It jumps from a 200 to a 400 amp rated distribution equipment. The only way to obtain a 350 size service is to install 400 amp equipment and fuse it at 350 amps. The standard size home distributions in North America today are rated at 200 amps. The cost of the service differs through out the continent. Ask your local electrical contractor for an estimate on an electrical upgrade to the required service that you want.
Amperage or Amps is a measure of is the flow rate of electrical current that is available.
To keep costs down, by special permission in the electrical code, for home wiring on a 120/240 volt system 2/0 is allowed. For any other type 200 amp service 3/0 that has a insulation factor of 75 or 90 degrees C is rate at 200 and 225 amps respectively.
Watts = Amps x Volts.
In North America an ordinary electrical receptacle is rated at 15 amps.
KVA is the abbreviation for kilo-volt-amp, or kilo-watt (volts x amps = watts) Your KVA is you amps used multiplied by 240 ( number of volts in the electrical service for your house) example: if your home draws 500 amps you are consuming you would be drawing 120,000 VA or 120 KVA. That help?
A 100 amp service will supply your electrical current needs UP TO 100 amps.When doing load calculations on a 100 amp panel it can only be loaded up to 80 amps.
In the electrical trade the only time there is a reference to start and running amps is when dealing with motors. The running amps is always lower than the starting amps. A 78 amp electric furnace will take a 100 amp service for it to operate and be within the electrical code guide lines.
Any lightning strike will burn out the service.

Amps is short for ampere, a unit for current.
The electrical current in a circuit is measured in amps.
The minimum recommended amperage for a house to run a dryer is typically 30 amps. However, it is crucial to consult the manufacturer's specifications and local electrical codes to determine the correct amperage requirement for your specific dryer model and household electrical system.
30-Amp Electrical Service
The formula you are looking for is W = E x I. Watts = Volts x Amps.
It depends on the size of the service to be installed. For a 200 amps service, a free standing mast is 2 inch rigid steel galvanized pipe and schedule 40 in strength.
