over here in the U.S.A, no not in the panel, however it would not hurt to put them there also, but by U.S.A. code it should have a GFCI box within 12 foot of the hot tub. read on and check out the site below, it will answer all your questions;;
Ground Fault Circuit : Interruption Protection (GFCI) GFCI protection is necessary in case anything electrical should allow electricity to leak to grounded metal in connection with the spa. This is especially possible if after years of use a heater element should rupture and the ground wire (that may or may not have been originally connected) should happen to become disconnected. A GFCI will sense this leakage and shut the voltage to the power pack oft. As of January 1, 1994, all equipment packs used with a spa or hot tub must be protected by a Class A ground fault circuit interrupter. This is called for in the N.E.C. code book in paragraph 680-42. If the equipment has a GFCI built into it,that GFCI may only protect certain components such as the blower, light ozonator, and sometimes the pump. The GFCI may not provide full protection, especially if the unit is wired for 240V service. To be sure, have a qualified electrician study the wiring diagram that came with your unit (or the manufacturer of the unit you are working on) for verification.
Keep in mind that when buying a 240 GFCI for an installation, be sure to get one that has neutral protection. The 60A Square D GFCI does not have neutral protection and therefore cannot be used on a hybrid equipment system. (Hybrid means the unit contains both 240V and 120V components.)
NOTE: Any GFCI protecting a circuit should be tested periodically to insure proper operating protection. If it fails to operate properly, it must be replaced.
240V Circuit Breaker : Installation There are two easily installed properly rated 240 volt GFCI breakers on the market today (as of the time this page was written). They are the Square D model QO 250GFI and the ITE Siemens model QF250, each rated for up to 50 amps. The square D 60 Amp GFCI can not be used with our equipment because it does not have load neutral protection. Most people who install the Square D GFCI breaker do not follow the instructions accompanying it. A common mistake is made by connecting their load neutral (from the equipment), the large white pigtail on the GFCI, and the power supply neutral to the connection block on the mounting bracket. The instructions show where the load neutral is supposed to attach to the GFCI. Before suspecting a pack malfunction, check the installation of this device (when used) and make sure it was installed correctly.
The connection points for the pack on the Siemens GFCI are more obvious, but again, make sure that only the load neutral is connected where indicated and that the white pigtail is only connected to the line service neutral.
here is site to tell you all about this, but remember this is U.S.A. codes, i have no idea on U.K.;;;;; I know some people will chime in and say i am wrong, but read this site and see for your self that i have infact told you the correct and lawful way to install the wiring to your hot tub!!!!!!!!!!!!!! so read this site below;;;
you need a rcb for the supply that covers live and earth.ask for the most sensitive trip you can get.cos electric water and humans dont mix well. Reply Rating: 0
