Panelboard and Switchboard Short Circuit Current Ratings

marked with their electrical ratings, including their SCCR. A typical marking would read, “Short-Circuit-Current Rating 65,000 RMS symmetrical amperes”. If the unit contains meter mounting equipment other than those for use with current transformers, they are also marked “Watthour meter not included in short-circuit-current rating”.

The Dielectric Voltage Withstand Test

The Dielectric Voltage Withstand Test page 4 Electrical and electronic devices also exhibit current analogous to leakage current during dielectric testing. However, since the dielectric test voltage is much higher, the current will be higher as well because the capacitive charging current increases in proportion to the increased voltage.

This trend is being driven in large part by the economics of PV system design. Average PV module sales prices have decreased to around 0.40 USD per watt peak (Wp). At the same time, other “balance of system” (BOS) costs, such as labor and cabling, now constitute a greater portion of the total installed cost of a PV system.
