120v ac at 100 " the wire is 000 AWG or BS longer length above it is unsafe. IS THERE A SOLUTION SURE 4 wires 0000 at 40 amps will do it for 110v single phase.
The size of wire for service entrance conductors for a 400 amp 3 phase service could be 500 MCM copper. This is very large size wire and difficult to bend and shape, to connect to terminals in the main disconnect and distribution panel. This problem is solved by using parallel conductors or on higher ampacities triple conductors. Using parallel conductors the wire size would be three ought (3/0) copper.

#2 Copper with TW insulation is required for 100 amp loads #3 Copper with R90 insulation is rated at 105 amps.
In the service distribution panel there are termination points at the top of the panel. Two of the utilities "hot" conductors terminate on the main breaker. The neutral utility termination point is on a terminal block usually off to the side near the main hot terminations. It is in this neutral termination block where the system ground connects from the ground rods to the distribution panel. For a 100 amp panel the wire size will be a #6 bare copper conductor.
For a distribution panel rated at 400 amps parallel runs of 3/0 conductors will do the job.

Need to know what size service is going to be installed at the end of the run.

Depends on the size of the sub-panel in that garage. If you are installing a 60 amp sub-panel 400 feet away from the main service panel then use AWG # 4.

Re Question with the voltage that you will be using.
If it was preinstalled, it may have been adequate at the time of installation. It depends on the power requirements of the home. If this is a new install, the NEC has a minimum of 100A for service equipment. To be honest, I would install 200A minimum to allow for future expansion.
