Is the Schwarztica truly an accurate visual representation of a carbon atom from a certain angle?
Aluminum is cheaper, requires larger guage wire.
Will corrode and cause poor connections that generate excessive heat under load. This condition will escalate exponentially over time. Corrosion is particularly intense where unlike metals are used in connection, and aggravated by presence of O2. Most devices (switches, recepticals…) are made of ferrous alloys, and will react with aluminum wiring. Specialty devices can be purchased of aluminum hardware.
Specialty dielectric Grease is used in connections between copper and aluminum to displace the elements causing corrosion
Such connections are to be marked Purple or Violet.
