A customer asked us to install a shower. We installed a new cable at the correct size and installed a 7.2 KW shower. We installed a cable and breaker that could allow for upgrade to a 10 kw shower in the future if they wanted a little more power to the shower. In this case the customer already had installed a working RCD. If not, then we’d have had to install a new RCD to meet regulations and keep our customer safe.
Our customer in the Carnforth area was provided with a hot shower that was installed correctly with a certificate to keep things in order.
