the bus bracing is sufficient. Bus Bracing Upgrades Many power systems incur changes over time and the short circuit capability of the system often exceeds the original rating of the switchgear. Modern circuit breaker technology incorporated into conversions can compensate for the high short circuit currents, but the bus system usually requires additional bracing to prevent

Retired Electrical Engineer - Power Systems Sep 26, 2008 #4 As Charlie pointed out, it all depends on how the switchboard was constructed. You need to check with the manufacturer. Many times they have a design level for bus bar bracing that is well in excess of the SCCR applied to the equipment.

Finally, the “bus bracing” is most commonly considered to be the momentary current expressed in rms asymmetrical current, because this equates to the historic usage of the “momentary” term. However, bus bracing may be expressed either in rms asymmetrical current (155 percent of IST) or in peak current (260 percent of IST), as either form demands the same performance from …

jraef (Electrical) 11 Jun 11 15:21 Just a pedantic clarification. Bus bracing is not to withstand the CURRENT, it's actually to withstand the MECHANICAL FORCES that will be created by the extreme magnetic field repulsion between bus bars under fault current conditions.

Bracing of Conductors in Switchboards and Current Transformer Compartments The purpose of bracing is to restrain the conductors from violent movement during fault conditions. Conductors not properly braced may pull out of their terminals and cause severe damage of the electrical equipment, which in turn could result in fire or personal injury.
