For one, cortisol is a primary anti-stress hormone. Without cortisol, you would go into shock and die if exposed to trauma. Cortisol also plays an important role post-exercise, by helping to supply fat in order to power muscle-protein-synthesis reactions. So cortisol is definitely not all bad.
Homes may also have sub-panels that are located elsewhere, which are smaller versions of the main panel and wired through it. Typical costs: Typically it costs $800-$1,200 to have a qualified electrician upgrade an existing panel to 100 amps, or $1,500-$2,500 if a new panel is needed. Expect to pay $1,300-$3,000 to upgrade to 200 amps, or $2,000-$4,000 to go to 400 amps. Installing a new sub-panel runs $500-$1,000.
The standard for household power used to be 60 amps. But modern homes may need as many as 200 amps to run air conditioners, computer equipment, high-definition televisions, and high-tech home automation devices. The cost of upgrading your existing electrical service panel to a 100- or 200-amp panel is $800 to $3,000.
