Capstone Turbine Corporation 21211 Nordhoff Street Chatsworth CA 91311 USA Technical Reference: Capstone MicroTurbine Electrical Installation 3.3. Overcurrent Protection & Disconnecting Devices Overcurrent protection is required for each microturbine, usually by circuit breaker or fused disconnect. This overcurrent protection device must be installed between the microturbine and the electrical service panel. The type and fault-current ratings of the device must meet maximum current and voltage ratings for each microturbine model as well as meet all local codes and specifications. Recommended sizing for overcurrent protection devices is as follows: Table 2. Overcurrent Protection Sizing Microturbine Model Recommended Trip Setting3 C30 C65 (UL, HUPS, and all other) C65 (CE) C200 C600 C800 C1000 60 Arms 125 Arms 150 Arms 400 Arms 1200 Arms 1600 Arms 2000 Arms If a fused disconnect switch is used instead of circuit breaker, time delay fuses are not required. Fast acting, current limiting fuses are recommended. It is recommended to install the fuses on the microturbine side of the switch. CAUTION: A lockable disconnect device should be located within sight of the microturbine. Any disconnect device should always have lockout provisions to facilitate safe maintenance operations. In the case that the service panel and microturbine are very near, it may be acceptable to use the overcurrent protection device as this lockable disconnect; please note that most circuit breakers will require additional hardware to become “lockable”. In the case of a long distance between the microturbine and the service panel, this should be a separate lockable switch. Figure 1 shows the recommended configuration for a four unit multipack of microturbines. 3 Recommended trip setting based on 125% of maximum microturbine steady state current as listed in the C65 Electrical Technical Reference (410001). For example, the nominal steady state current of a C200 is 310 Arms. 125% x 310 Arms = 387.5 Arms. This is rounded up to 400Arms. 410009 Rev F (October 2013) Page 8 of 31 Capstone reserves the right to change or modify, without notice, the design, specifications, and/or contents of this document without incurring any obligation either with respect to equipment previously sold or in the process of construction.PDF Image | Technical Reference Capstone MicroTurbine Electrical Installation
