- Why Is Junction Box Creepage Distance Getting Harder in the 1500 V Era?Clearance and creepage are always mentioned together, but they guard against two completely different failures. We explain what creepage distance is, how working voltage, pollution degree and material CTI determine it, where it applies in a junction box, and why in the 1500 V era it has become a hard constraint on housing materials and design.
- What a Junction Box Does: Functions and RolesThe four jobs of a PV module junction box - power output, bypass protection, sealing and electrical safety.
