General Capacitor Specification
Voltage Ratings A capacitor''s voltage rating is an indication of the maximum voltage that should be applied to the device. The context of the rating is significant; in some instances it may indicate a maximum safe working voltage, in others it may be more akin to a semiconductor''s "absolute maximum" rating, to which an appropriate de-rating factor should

6 FAQs about [Capacitor flat iron grounding specifications]
How do you ground a pad-mounted capacitor bank?
Each pad-mounted capacitor bank is supplied with a two-hole NEMA pad for grounding. Connect a suitable size conductor from the two-hole NEMA pad to the ground as indicated on assembly drawings.
What are the requirements for equipment grounding?
The requirements for equipment grounding are expressly specified in the National Electrical Code (NEC ) NFPA 70 1 as follows: Conductive materials enclosing electrical conductors or equipment, or forming part of such equipment, shall be connected to earth so as to limit the voltage to ground on these materials.
What is the maximum ground current limit for a grounding resistor?
For utilization equipment at less than 1000 V, the maximum ground-current limit must be 25 A or less, but common practice is 15 A. The 100 V maximum frame potential limit (for sizing the grounding resistor) applies to surface or underground utilization equipment greater than 1000 V.
What is the point of grounding for a low-voltage system?
The point of grounding for systems shall be the neutral or common conductor where one exists; otherwise the point shall be a phase conductor. On systems over 1000 V, a transformer-derived neutral may also be used as the attachment point for a system ground. This method is not mentioned for effective grounding of low-voltage systems.
What is system grounding?
System grounding. The grounding of some part of the electrical power supply sys-tem, usually the system neutral. Equipment grounding. The grounding of all the metallic equipment and enclosure frames, through bonding of all component parts and their connection to ground. Signal common grounding.
What is effective grounding?
Effectively grounded systems will have a line-to-ground short-circuit current of at least 60% of the three-phase, short-circuit value. In terms of resistance and reactance, effective grounding of a system is accomplished only when R0 <= X1 and X0 <= 3X1 and such relationships exist at all points in the system.
