What’s the difference between a single-phase ( Residential ) or three-phase ( Industrial ) electricity supply?
Both of these are electricity supplies from your current supplier, it’s the amount of power that is different. A single-phase supply is smaller than a three-phase supply meaning you cannot use as much power. A typical house will need a single-phase supply whilst a larger house, flats or commercial building will need a three-phase supply.
The way to tell what supply a property has is by looking at the fuse on the service head.
Single-phase has one 100amp fuse this will give you 240v, Fuse to Neutral
A three phase supply, has three 100amp fuses ( This can be larger depending on your demand ) Where a 3 Fuse system will give you 240v for each fuse to neutral but 415v fuse to fuse..
Hi Mark, Very pleased with the panel you built up for us and the way that is was packed, excellent and you understand the issues of couriers and how the contactors etc could be flung off etc. Well done.
Thanks for the response, in fact it is now working perfectly, the generator required to be in OFF mode to shut down from the ATS control. Fantastic product, thank you. Patrick
