Electrical:

• All electrical wiring must be sized and fused appropriately for the current it will carry to prevent electrical fires. ``Home built" low-voltage high-current power supplies for wire- chamber readout electronics typically have a single ground return. The ground return must be sized to carry the current of all supplies that use the common return.
• Do not lay signal cables in power cable trays. Power cable trays contain magnet or other high current power cables. Signal cables must be either laid in a separate (signal cable) tray or must be separated from the power cables by an approved fire barrier. Consult your safety warden before laying cables.
• Do not lay or attach flammable gas lines in any cable tray (power or signal).
• Do not lay or attach extension cords or SO type cord in cable trays.
• Do not modify or add to a building electrical distribution system. All electrical work must conform to the National Electrical Code and be performed by qualified electricians.
• Do not use cube taps to expand the number of available 110 VAC outlets. Plug strips with circuit breakers are available in the stock-room and are allowed.
