A standard 9–10kW electric shower typically requires 10mm² twin and earth cable on a dedicated 40A or 45A circuit. Larger 10.5kW+ showers may need a 50A circuit breaker. The exact specification depends on your shower model and the cable run length. We specify and install the correct cable for your installation.
