I'm designing a circuit which should leak some amount of current from AC line to PE. The question is regarding clearance-creepage calculation for this specific case.
The part (triac optocoupler) is rated for 600V peak on TRIAC terminals, but the pin spacing is below minimum required by safety standard (2mm instead of 3mm required from line to PE).
The question is if I can count clearance-creepage added by each resistor leads spacing?
For example: If I have 4 resistors of 1206 size it will give me ~4x1.5mm=6mm donated by resistors + 2mm pin spacing of triac optocoupler.
The most intuitive answer will be yes, but in case triac is not conducting we will have line voltage at its terminals and it can probably arc the leads.
Thank you in advance.
