Grounding & RCD — FAQs

Do all outlets need RCDs?

Wet areas and socket circuits typically require RCD/RCBO protection to reduce shock risk. We design selectivity to avoid nuisance tripping.

Is one ground rod enough?

Not always. We test soil resistivity and design electrodes/bonding to meet target earth resistance for your site.

Why does my RCD trip randomly?

Could be leakage currents, mixed neutrals, or wrong RCD type. Our audit finds and fixes root causes.
