Installation requirements for pigtail termination boxes
Install termination beginning at cable jacket edge for tape or wire shielded cables. See Table 1 on cover for maximum. The MK2 Ultra Compact Termination Box is designed for use in residential and business applications for the termination of up to two fibres. The wall box enables the installation of a small cable to be spliced to up to two SC pigtails (PC or APC), which connect to shuttered adapters at the base of. The wall box enables the termination of a customer drop cable onto SC/UPC or SC/APC type pigtails and adapters. This method involves using a short length of conductor to join multiple circuit wires to a single device terminal or to consolidate several wires together. When. For shielded (Tape, Wire or UniShield®) and non-shielded cables Working around energized systems may cause serious injury or death. De-energize and ground all electri-cal systems. When a device or outlet requires replacement, having wires joined by pigtails allows you to disconnect and reconnect components without disturbing the rest of the wiring. This convenience reduces the chance of errors or damage during maintenance.
