R.C.D. Immobilising Electrical Appliances.

Zoomup

They should be banned. Any electrical appliance that immobilises an installation R.C.D. should not be made. The deficiency should be engineered out of the design of the appliance. Imagine a loved one being electrocuted in the garden because the house R.C.D. was blinded and became inoperable by the vari-speed motor washing machine.

Imagine adding an accessory to your car and then finding that the brakes don't work. It is the same situation.

 

BAN 'EM.

    But all of those examples are not a smooth DC, but rather an AC with a DC offset or if you prefer to call it that, a “pulsed” DC. And a short to earth within such a device would still operate a type A RCD, and as the diode is likley to blow short or open pretty smartly, the fault is then removed - either by diode failure or a type AC RCD.
