Underground Service Work
Class 2D Accredited Level 2 electricians for underground service mains, consumer mains upgrades, and cable fault location — from the pit or pillar to your switchboard.
Class 2D accreditation authorises Level 2 electricians to install, repair, and upgrade underground consumer mains — the cable run from the network pit or pillar to your main switchboard. This is network-side work that standard electricians cannot perform, and it must be completed under Ausgrid or Endeavour Energy authorisation with compliance to AS/NZS 3000 and AS/NZS 3008 cable sizing requirements.
Why choose us for underground service work?
Licensed electricians, rigorous safety standards, and clear communication from quote to handover
