There is no telling from your question. Each situation would be different. Modern systems would use breakers rather than fuses.
You should not load a 125 amp panel any more than 100 amps.
Depends on the size of the service. 100 amp service will require 3 gauge, 150 amp service will require 1/0 gauge, and 200 amp service will require 3/0 gauge.
A 100 amp residential service requires a size #8 copper wire, it should be insulated in green.
For Service Entrance Cable 600 kcmill (Thousands of circular mils).
Yes, the wire size has to be increased. The existing 100 amp service will now probably have a #3 conductor with an insulation factor of 75 or 90 degrees C which is rated for 100 and 105 amps respectively. Increasing to a 150 amp service will use a #1/0 wire size. If you are thinking of an upgrade, skip the 150 amp service and go to a 200 amp panel. New homes are installing 200 amp 42 circuit panels. The extra cost is only reflected in the materials as the labour costs will be the same regardless whether a 150 amp or a 200 amp panel is installed. The wire size for a 200 amp panel is #3/0. With an insulation factor of 75 or 90 degrees C the rating is 200 or 210 amps respectively.
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.
The maximum current capacity of a 100 amp service panel is 100 amps.
You should not load a 125 amp panel any more than 100 amps.
A 100 amp service provides less electrical capacity than a 200 amp service for a residential electrical system. This means that a 200 amp service can handle more electrical load and is better suited for larger homes or homes with higher electricity needs.
In how many amps of current before blowing out. 2 amp 5 amp 10 amp 15 amp etc.
The underhood fuse box. its either an 80 amp or 100 amp fues
For a 100 amp service in copper, a wire size of 3/0 AWG should be used.
You can install a 100 amp sub panel off a 60 amp main panel fed by 100 amp service. This allows for the sub panel to be adequately powered with headroom for future circuits or expansions. It is important to ensure the wire size from the main panel to the sub panel is sufficient to handle the load.
No, each size service needs its own meter base.
The recommended copper wire size for a 100 amp service is typically 3 AWG (American Wire Gauge).
For a 100 amp service, it is recommended to use aluminum wire that is at least 2 AWG in size.
The recommended wire size for a 100 amp aluminum service is typically 2 AWG (American Wire Gauge).
