Not sure what you mean by "gas" rated wire. If you mean "gasoline resistant" you probably have type THHN wire insulation. Size #8 THHN is not suitable for a 60 amp application anywhere.
The kitchen and garage are the only 20 amp circuts usually.
Rated for exactly 60amps you will find limited breaker spaces due to the rating of the hardware used in it's construction and air circulation restrictions from the equivalent limited enclosure area. When rated at a determined amperage level it is required to construct the device based on the worse case possible scenario which includes a continuous running load. This will determine it's minimum standards according to local and national codes for hardware, room, spacing, and, layout. This does not limit you to only this size panel though. As long as you install the 60amp breaker first in your house panel anything installed down stream {from the load side of the 60amp breaker will be protected up to 60 amps. Therefore you are permitted to exceed those ratings and still remain within code because regardless of what your load is, it can not exceed 60 amps without tripping the breaker. You can install a 12/24 {12-full size or 24-half size [mini's]} 100amp panel for additional breaker spaces and the cost difference is negligible. One code issue to consider is if the sub panel in the garage is not in line of sight of that 60amp breaker then you might want to install another 60amp breaker in the garage panel to interrupt the incoming power giving you the ability to work on/in the garage panel without the possibility of someone re-energizing it mistakenly. I would suggest before this to consult with an electrician for a load calculation to determine if there is 60amps of available power in the 100amp panel in the home. This panel may not have an over-current 100amp main breaker which means it is possible to exceed the panel rating of this unprotected panel. Installing a 100amp over-current device {breaker, fused safety switch, fuse block etc...} like your 60 amp breaker to the garage it will limit the total load to only 100amps. Good Luck and obtain all permits and full understanding of the project and safety protocols in it's regards.
A 100 amp panel should have a conservatively rated busbar and wiring but this says nothing about your particular panel. If you are asking a question relating to safety it needs to be seen by an electrician.
In North America the smallest size breaker found in a home distribution panel is rated at 15 amps
A #1 aluminum wire with a insulation factor of 90 degrees C is rated at 105 amps. Three #1 wires can be installed into an 1 1/2" conduit.
It has to be a fire rated door.

In theory the maximum amount of power arriving from the sun is about 1.3 kilowatts on every square metre. The standard 1.6 square metre solar panel such as installed on roofs in the UK is rated at 220 watts.

If you have a measured continuous load of say 80 Amps, you would want to have a panel rated at 100 A. For continuous load you want to be at 80% of rated capacity.
Linksys is a very good router, however, their security is a little low if you don't install and change the passwords. Most of the linksys routers have a control panel that comes pre installed with a generic admin admin password.
