Can anyone enlighten me.
I am installing a slot meter and CU for a customer who got stung with a huge electric bill from students.
The supply cables and cpc to the new meter will be about 4.5m and will be enclosed in 25mm²x40mm² mini trunking together with 6mm² Cooker cable, 2x2.5mm² Ring and 1mm² lighting.
I am installing a 100A DP isolator in the original CU and had intended using 16mm² for the feed.
I was told by the wholesaler that you're not allowed to fit 16mm² it has to be 25mm².
I know OSG says meter tails must be 25mm² but does this apply to extended supplies
