A permit in Tucson can run up to 95 dollars depending on the size of the installation. The best way of finding out a price of the permit is to ask an electrical contractor for an estimate on the job that you want done. Ask the contractor what the cost of the permit is, as a break out price. If the contractor says that you don't need a permit then move on to another contractor. It is in your best interest to obtain a permit and get the job inspected by an inspector. That way if anything goes wrong after the installation is finished and the insurance company gets involved, you won't get blamed for an illegal wiring installation that had never been inspected.
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.
The top of the service panel can be no more than 6' 6" off the floor. Must be 36" of clearance in front of the panel and 30" on each side. Use common sense when installing the panel. If you install the top of the panel aroud 6' 2" off the floor you are good to go.
A 200 amp service panel with a 60 amp sub-panel.
yes The meter rating is the maximum, if you use it on a smaller service that is OK from a code point of view. However, the local utility company may also have special rules about which meters pans can be used on which type installations. You may need to check with them
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.
It is inserting a breaker into a service panel.

1) If you are tripping the main breaker and you do not have an electrical fault in the home. 2) If you are installing additional circuits or appliances and you expect to exceed 80% of the load capacity of the existing service panel.
You should always label the circuits in the panel you just installed.
If your goal is to standardize the fastener length when you have varying gages. If it's an access panel with several grip lengths you will risk installing the wrong gripped fastener when you reatach the panel.
Open driver's door, fuse cover is to the left from the steering wheel on the front panel (it is covered by the door when door is closed)
You should always label the circuits.
The place where the power drop from the electric company enters your house. The service panel is where the fuses or breaker switches are.
Installing solar panels in someone's home usually involves installing multiple panels, which can have a costly upfront price. This is because there are few inverters that can work with a single panel.
You have two options, one is a complete service change. The average house service these days is 200 amps 42 circuits. The second option is to install a sub panel off the existing service. Depending on how many circuits you need will govern the size the sub panel. Here is where it gets tricky. Two side by side single pole breakers or one two pole breaker will have to be removed from the original service panel and replaced with a new two pole breaker. The size of this breaker will be governed by the total load of the new sub panel. The wire from the new sub panel to the two pole breaker is also governed by the load of the sub panel. As an electrician I would recommend that you not do it yourself but get a qualified electrician to do it for you. He would (should) take a permit out for the job and get it inspected.
