Key figures
Rules in Ireland
A home charger of up to about 7 kW usually fits within the standard 12 kVA supply (Maximum Import Capacity), so no upgrade application to ESB Networks is needed; if you would exceed it, apply online for a 16 kVA connection. Most Irish homes are single-phase, so 7.4 kW (32 A) is the typical maximum.
