Interrupting Rating vs Short Circuit Rating: A Quick Comparison
This is the interrupting rating, and the 2023 version of the NFPA 70, also known as the National Electric Code or NEC, gives the definition of the interrupting rating in Article 100 as the highest current that a device is identified to interrupt at a rated voltage under standard test conditions.
Crystals and load capacitance
Let''s say you have a Crystal rated with 8pf Load Capacitance. So how do you know which capacitors to use? Easy. Every crystal datasheet lists something called the Load Capacitance (CL). In the case of the crystal above, it''s 8 pF. C1 and C2 need to match this Load Capacitance, with the following formula being the key:

Considerations When Switching Capacitor Banks
When capacitor banks are installed in a back-to-back arrangement (two or more capacitors close to each other), the energization of the second bank looks like a short circuit to the first bank. This causes the first capacitor bank to discharge into the second capacitor bank resulting in high inrush currents.

How Distribution Capacitor Banks Compensate for Inductive Loads
True to their name, reactive loads spend half of their time performing an "Action" - removing energy from their circuit and storing that energy in their fields (a magnetic field for the inductor and an electric field for the capacitor) – and the other half of their time performing their "Reaction" - returning that stored energy back to their circuits.

How to calculate the value of crystal load capacitors?
For example, if the crystal load capacitance is 15pF, and assuming Cstray=2pF, then: CX1 = CX2 = 2(15pF - 2pF) = 26pF . It is difficult to know exactly what the stray capacitance is, but if you find the oscillation frequency is too high, the load capacitor values can be increased. If the frequency is too low, the load capacitors can be decreased.
