Puritan Ground Master (Earth Line Interference Eliminator)
Why you'll love the Puritan Ground
The benefits that matter, at a glance.
Effective Interference Elimination
The Puritan Ground Master (Earth Line Interference Eliminator) addresses the challenge of high-frequency interference on the Earth Line, ensuring stable and silent ground connections for optimal system performance.
Modern Electrical Appliance Compatibility
With the prevalence of modern appliances using high-frequency switching power supplies, which often dump interference onto the Earth Line, the Ground Master provides a solution to mitigate this issue.
Safe and Legal Solution
Unlike traditional methods involving additional ground rods, which pose safety risks and may contravene UK Wiring Regulations, the Ground Master offers a safe and legal alternative.
Elimination of Undesirable Noise
The Ground Master efficiently removes undesirable noise and disturbance frequencies on the Earth Line without compromising the effective route to ground.
Enhanced Safety
When used alongside an additional ground rod, the Ground Master safely isolates potentially dangerous mains frequency currents while allowing offending noise frequencies to be efficiently eliminated.
Installation Notes
A single-core cable is required to connect the Ground Rod to the Ground Master. Depending on soil type, additional improvements can be achieved by using multiple Ground Rods spaced at least 1.2 metres apart. Regular watering of the area during dry spells enhances performance, and moisture-retaining materials like clay or conductive aggregates can further improve results.
