Has your electric shower stopped working or is not very powerful? When upgrading or installing a new electric shower, understanding the relationship between your shower's power output (measured in kilowatts) and the rating of the circuit breaker in your consumer unit is crucial. This guide will help you navigate these considerations to ensure a safe and efficient setup for your Newton Abbott home. But remember is you are struggling to choose the right electric shower, or you are unsure, don't hesitate to ask for advise.
Understanding Electric Shower Kilowatt Ratings
The power of an electric shower is measured in kilowatts (kW). The higher the kW rating, the more powerful the shower, providing a higher flow rate and hotter water. However, the power output of your shower must be matched with the correct circuit breaker rating to prevent overloading and potential electrical hazards.
Here's a general guideline on how the kW rating of an electric shower correlates with the circuit breaker rating:
- 8.5 kW Shower: Requires a 32-amp breaker
- 9.5 kW Shower: Requires a 40-amp breaker
- 10.5 kW Shower: Requires a 45-amp breaker
- 12.5 kW Shower: Requires a 50-amp breaker
Why Matching Matters
Electric showers draw a significant amount of power. Using a circuit breaker with an insufficient rating for your shower can cause the breaker to trip frequently or, worse, lead to overheating and electrical fires. Therefore, it's essential to ensure that your consumer unit can support the electric shower you plan to install. But please check the breaker because just that old shower was 9.5kw shower or 10kw shower doesn’t always mean you can go for the same output.
Checking Your Existing Setup
Before purchasing a new shower, check the rating of the existing circuit breaker dedicated to your shower.
Here’s how you can do this:
- Locate Your Consumer Unit: Find your home’s consumer unit (fuse box). This is typically located in
a utility room, garage, or under the stairs. - Identify the Breaker: Look for the breaker that controls the shower circuit. It should be labeled
accordingly. - Check the Rating: The breaker will have its amperage rating marked on it (e.g., 32A, 40A, 50A).
Cable Considerations
The cable size also plays a crucial role in determining the maximum kW rating of your shower. If the existing cable cannot handle the higher current required by a more powerful shower, it will need to be upgraded.
Standard cable sizes typically used are:
- 6mm2 cable: Suitable for up to 8.5 kW to 9.5 kW showers
- 10mm2 cable: Suitable for up to 10.5 kW to 12.5 kW showers
When to Call a Professional Electrician
While it’s helpful to understand these basics, installing or upgrading an electric shower involves complex electrical work that should be performed by a qualified electrician.
They can:
- Confirm the existing cable size and breaker rating
- Upgrade your consumer unit or cable if necessary
- Ensure compliance with all relevant safety regulations
- Remember electrics and water do not mix
- Electrics are dangerous if poorly connected or lack of safety devices.
