Mayfield company Protex has designed a world-first electrical safety product that would allow someone to put a knife into a ‘‘live’’ toaster for as long as they liked without incident.
That safety technology alone is not a world first, but applying the residual-current device to a domestic power board and then into a generator without changing the motor characteristics is, according to Protex executive director Wayne Callen.
‘‘It is a world first for a safety product that isolates an isolated product,’’ Mr Callen said.
‘‘It picks up the fault and takes the isolation of the electrical circuit to the next level. We take the human element out of it and you could stick a knife into a toaster and stand there for as long as you like and nothing would happen.’’
The earth wire is designed to protect against electric shock but will travel through the ground of the human operating with electricity in water or when there is a fault.
Protex provides the revolutionary unearthed and improved earth-based electrical solutions on construction sites and households. The product is being used for the first time on a commercial project at the University of NSW on the construction of its Solar Industrial research facility.
Protex has been working specifically on electrical safety solutions since the company started in 2003 and is hoping for a return to investors after worldwide attention to the product.
