Clarity on wire thickness

Featured Replies

Hi all

Need some guidance in the wire thickness from DB to inverter and inverter back to DB. Not that I don't trust my electrician, but his proposal seems a bit excessive. He proposed 10mm wire.

Would appreciate some guidance.

5KVA Mecer inverter

Distance from inverter to DB is 16m

Planning to run house lights and a few dedicated plug points

Yes 10mm² is overkill for 5kw inverter. I would run 6mm² for the inverter output and 6mm² to the input of the inverter. 30 amp Mcb.
