User manual FURMAN ACD100

[. . . ] The breakers are of the highest industrial grade, UUCSA listed, precise in operation and rugged in construction. The ACD 100 provides basic spike and surge suppression, with metal oxide varistors (MOV's) connected between the hot and neutral conductors of each circuit. The MOV's respond to line derived spikes in less than a nanosecond, clamping transient voltages to safe levels of 250V or less. * Pulse tolerance is defined as the maximum peak current amplitude of a single half sine wave pulse of 8 ms. duration that will not trip the circuit breaker GENERAL INFORMATION Congratulations on your purchase of a Furman ACD 100 AC Power Distro. [. . . ] The gauge and number of conductors depends on the supply voltage and cable or wire bundle length. Consult Table 1 below to select the cable type best suited for your application: # Of Conductors Current Ground Carrying Including Conductors Conductors Ground 120V 240V ** 3 4 4 AWG 6 AWG 8 AWG 8 AWG 10 AWG 12 AWG 208V 3-ph *** 5 TABLE 1, REQUIRED WIRE GAUGES The "Current Carrying Conductor" and "Ground Conductor" columns give the minimum recommended AWG size for cable lengths of 100 feet or less. Note that while it is acceptable for the ground conductor to be a smaller gauge than the current carrying conductors, many cables have all conductors the same size. If they are all the same size, it must be the size specified in the table for the current carrying conductors. * Including ground, assuming the system neutral must be kept separated from the safety (chassis) ground. ** Assumes three 20 amp loads on one conductor and two 20 amp loads on the other conductor. *** Assumes two 20 amp loads on each of the first two conductors and one 20 amp load on the third conductor. -3- ACD-100 / AC POWER DISTRIBUTION The ACD 1 00's strain relief clamp can accommodate a cable up to 1. 5 inches in diameter. For reference, a 4 conductor, 2 AWG type S or SO portable cord's diameter is 1. 28 inches. If the cable is to be moved from location to location frequently, we suggest you make it at least a few yards longer than the length needed for the most distant location. This is because the'vow source end will typically be left as "pigtails" that is, with the outer jacket stripped off a few feet and no connectors attached. When the electrician makes the connection to the power source, he or she will often cut a few inches off each conductor to expose clean copper to assure a reliable connection. After threading the cable end through the strain relief clamp, connect the stripped conductors to the buss bar block. Be sure to put each wire in the lower part of its terminal, so that it is compressed above and below by copper rather than by the set screw itself. Prepare and connect the cable: The supply cable will be connected to the ACD 100's buss bars via terminals that secure the individual conductors with set screws. When removing the outer jacket, be careful not to nick or cut into the insulation of the individual conductors. When stripping the individual conductors, be careful not, to cut through any of the copper strands. 4. Divide the load: If there is more than one hot wire, the five 20 amp loads must be split among them and balanced as well as possible. This is done by reconnecting the wires from the buss bars to the five circuits. There are two wires to each circuit, a hot (black) and a neutral (white). Each black wire is labeled with a letter (A, B, C, D, or E) corresponding to the circuit it goes to.
