This query is in relation to power factor correction (PFC) units.
The PFC unit was installed as part of a new build in 2016 for a secondary school. There has recently been an incident connected to the ongoing maintenance of this asset, and I’m now reviewing what the actual drivers and requirements are for its inspection and maintenance regime.
I’ve identified SFG20 ref. 40-03, which sets out 12-monthly tasks for PFC units. I’m also looking at how the requirements for routine inspections under Guidance Note 3 would extend to the PFC unit itself, and whether a 6-monthly check (as per Table 3.2) would be appropriate or expected.
The panel builder is Kane and EPCPS were the PFC manufacturer, but their documentation isn’t particularly clear on what maintenance is required or at what intervals.
I wanted to reach out to see if anyone has experience with this and can advise:
-
What drivers under BS 7671 (and related guidance such as GN3) you use to justify inspection and maintenance intervals for PFC units, particularly in an education environment.
-
How you set appropriate maintenance thresholds/frequencies to demonstrate good industry practice when manufacturer guidance is limited or vague.
Any practical examples, references or approaches you’ve used would be very helpful.
