Configuring internal capacitors for crystal oscillator
Are the factory trim XOSC32MTRIM values set by nordic before the chips are delivered or are they part of a calibration procedure that must be done by end customers? Sign in to reply; "The load capacitors should be somewhat 2 times the internal capacitance - 4. Which means that the parallel load capacitors should be (2*8pF -4pF)= 12 pF"
[AC] Replaced capacitor, now unit tripping plug breaker?
Run capacitors do not hold a charge when the compressor is off, they discharge themselves through the motor windings of the compressor. When not in the circuit, a motor winding is just an electric resistor. If you get shocked by a run capacitor or it ever does have a spark then there is usually something wrong with the motor it''s hooked up to.
Impact of different oscillator capacitors
A manufacturer of nrf52832 module has replaced by mistake the values of C1.C2 capacitors that are connected to the 32Mhz oscillator from 12pf to 24pf and 27pf. Nordic Case Info.

The main circuit breaker for the North Tower of Lumiere Residences tripped off, causing a power outage. The circuit breaker services the elevators, CCTV, and common area lighting. Security reported the outage around 6:50PM on May
Capacitor Tripping Problem
Yes, it surely will. When you connect the first capacitor, the impedance of the bus keeps capacitor charging currents low. But, when the second bank is connected, the impedance will be extremely low (impedance of the two capacitors) and the corresponding current will be high. This will trip modern breakers with electronic/digital tripping devices.

What is a capacitor trip device?
A capacitor trip unit is a prepackaged module that supplies power for tripping an AC controlled circuit breaker with discrete relays following the loss of the AC control voltage. This model protects against losing power for time period up to 2 days by having a small gel cell battery support the voltage.
