Hi,

I have bought a DeLonghi Fivy 1800w radiator, which has no earth wire. Do I need an RCD for this? (Thinking of putting an inline one on the lead).

If so, which type should I look for? I've read some work by detecting current on the earth lead, whilst some work by detecting an above-threshold current differential between the live and neutral leads - or do they all work both ways?

Many thanks,

Jay
 
It's specified as double insulated so doesn't need an earth and can be safely used on a two core flex.

Modern RCD work on current differential. Very early ones detected earth circuit current, or more accurately rising voltage of the circuit earth.

Understood Geoff, many thanks for your guidance.
