| Most hot tub spas require a 230 Volt 32 Amp feed but smaller, less powerful spas would accept a 230 Volt 20 Amp or 13 Amp feed and should be protected by the correct rating of fuse or circuit breaker (MCB) and a recognised means of Earth leakage protection (RCD) or a combined unit (RCBO). The cable termination (Enclosure, isolator or socket) should be made to IP56 if possible but we would recommend IP66 if the termination was mounted externally. The termination should offer a means of isolation at least 2 Metres away from the nearest point of the hot tub spa. In all cases the electrical installation must be carried out by a qualified electrician and amendments to the Building regulations now mean that the installation will require a test (Part P Certification). If the electrical contractor is NIC EIC approved the test and inspection would be automatic, if not the electrical contractor would have to carry out the test, but only if they are Part P certified. Otherwise, they have a legal obligation to engage a certified electrical contractor or body to carry out the test and issue the necessary documentation and certificate to attach to your home owner documents to prove the test was carried out on the circuit to any potential future house buyer. Consideration should also be given to any additional power requirements such as power sockets and garden lighting. It is also a good idea to install a supply greater than the immediate requirement for future expansion, this would prevent having to disturb your garden or interior decoration at a later date. |
