• Electrical wire sizes Diameters Wire Size Tables for

  Excerpt To avoid excessive voltage drop select a size wire that will minimize voltage drop You need to know the length of the wire run and the amp load or current that will be on the circuit. To determine amps add up the wattage of all electrical devices that will be on the circuit and divide this total by the voltage of the circuit 110 or 220.

   · Double-stuffing has its limits. In addition to any limits that your loadcenter places on the use of double-stuff breakers there are also limitations on the breakers themselves due to the smaller effective frame sizes involved. As you have noticed one of those limits is that double-stuff is incompatible with AF or GF functionality or with other special functions/ratings such as the HID

• What is ESD Electrostatic Discharge Safety Prevention

   · ESD stands for Electrostatic Discharge.Static electricity is an electrical charge that is at rest. This is mainly created by imbalance of electrons that stay on a specific surface or in the environmental air. The imbalance of electrons (in all cases is caused by absence or surplus of electrons) thus causes an electrical field that is capable of influencing other objects at a distance.

   · The amount of heat that can be transferred through the air is limited and will generally be less than conduction. The thermal conductivity ( K _ s ) of the polymer substrate is normally low leading to the substrate close to the hot wire quickly heating up and energy being transferred away from the wire slowly. Therefore heated wire from a tool can melt a substrate instantly around the wire penetrating it
