Installing an SSVR with Heat Sink on Rear Side of Plastic Panel in Switchboard – Compliance Question

[js9658]

Hi everyone,

I have a question about the technical compliance of installing a solid-state voltage regulator (SSVR) with a heat sink on the rear side of a plastic panel inside a switchboard. The SSVR has exposed terminals, and since installing it on the front is not allowed under Australian standards, I want to ensure everything is above board with the AS/NZS 3000 standards for mounting it on the rear side of the plastic panel.

From my understanding, this setup should be technically permissible if:

1. The installation complies with all safety, heat dissipation, clearance, and accessibility requirements.
2. The plastic panel is heat-resistant and capable of handling the heat sink and SSVR.
3. The installation doesn’t interfere with the safety or operation of other components within the switchboard.

I’d like to hear from anyone who’s done something similar or has insight into compliance for this type of setup. Are there any potential issues or additional requirements I should be aware of?

Looking forward to your advice!
