Got RCDs? They must be tested and recorded
SafeWork NSW says RCDs used at work must be tested regularly by a competent person, and records of testing (other than push-button tests) must be kept until the device is next tested or disposed of.

Dann's Electrical upgrades commercial switchboards for shops, offices, warehouses, schools and strata across Penrith and greater Sydney. Your load is worked out first, with power logging if needed, so the new board has room for more circuits. Work is done after hours to keep you trading, and switchboards Dann's installs carry a 25-year warranty.
An undersized or outdated board causes nuisance tripping, and stops you adding equipment. We upgrade commercial boards with modern protection, room for more circuits and clear labelling.
We work out your current and future load first, with power logging if needed, so the new board isn't full on day one. Work is scheduled after hours to keep you trading, and switchboards we install carry a 25-year warranty.

Switchboard compliance
Safety switch, testing and licensing duties from SafeWork NSW.
SafeWork NSW says RCDs used at work must be tested regularly by a competent person, and records of testing (other than push-button tests) must be kept until the device is next tested or disposed of.
SafeWork NSW says RCDs are designed to immediately switch off the supply of electricity, protecting against the most frequent cause of electrocution.
SafeWork NSW lists making sure only appropriately licensed or registered electricians carry out electrical work as a key way businesses control electrical risk.
Where we work
We travel all across Sydney for commercial and industrial work. We look after sites in Wetherill Park, Kemps Creek and the western industrial precincts, as well as Penrith, the Blue Mountains and the Hawkesbury.
Common signs are frequent tripping, no room for new circuits, old fuses, no RCD protection, heat or scorching, or plans to add equipment, air con or a kitchen. We can thermal-scan the board and log the load to give you a clear answer.
We schedule the switchover for after hours or weekends so you keep trading, and tell you exactly when the power will be off.
