Type F and Type B RCDs are not two price levels of the same device. They are designed for different residual-current waveforms. For an EV charger, Type F can be used only when the complete arrangement—including suitable DC residual-current detection—is…
A Type B RCBO and a Type B RCCB can provide the same residual-current type, but they do not provide the same circuit functions. The RCBO also trips for overload and short circuit, while the RCCB normally needs a separate…
A home EV charger normally needs a dedicated circuit with overload, short-circuit and residual-current protection. The correct RCBO cannot be selected from charger power alone: you must also check the EVSE manufacturer’s instructions, built-in 6 mA DC detection, cable capacity,…

How Proper Protection Coordination Saved a 500kW Installation from Catastrophic Failure The $50,000 Mistake That Could Have Been Avoided Last month, we received a frantic call from a solar installer in Arizona. His 500kW commercial rooftop system had just experienced…
L'erreur de $50 000 qui aurait pu être évitée Le mois dernier, j'ai reçu un appel affolé d'un installateur solaire de l'Arizona. Son système de toiture commerciale de 500 kW venait de subir une perturbation du réseau - rien d'inhabituel. Mais voici ce qui s'est passé : lorsqu'un...
Le cas tragique de Kuala Lumpur : Quand la RCCB n'a pas voyagé 15 décembre 2022, Kuala Lumpur, Malaisie - Un homme de 34 ans, père de trois enfants, est entré dans sa salle de bain pour prendre sa douche matinale. Quelques minutes plus tard, sa femme l'a trouvé inconscient sur le sol, le...
The $50,000 Mistake That Could Have Been Avoided Picture this: A solar farm project manager in Arizona just watched his entire DC distribution panel go up in smoke. The culprit? A batch of substandard DC surge protective devices (SPDs) from…
