We can liaise with your electrical contractor regarding
the exact specification for your chosen hot tub model.
However, you must meet the following specification:
• The hot tub should be appropriately protected by
a sufficiently rated MCB (main circuit breaker) and
should cover the maximum amperage pull of the
hot tub. A hot tub that has a maximum current
draw of 30 amps should be fitted with a 32amp
MBC. The serge current of the pumps (i.e. the
rush of current when pumps are first turned on)
can play a factor within the electrical install. Some
installations may require a type c MCB, but this will
be decided by your electrician.
• Your hot tub should be protected against earth
faults also, by an RCD (residual current device).
This is a trip switch which works to prevent
the danger of electric shocks from damaged or
waterlogged cables and connections. A suitable
rated 30Ma RCD is what is recommended.
• Any outdoor cabling should be suitably protected
from damage by either laying protective ducting (pc
pipe) below ground or by using a SWA (steel wired
armoured) cable. Your electrician will calculate the
size of cable required dependent upon loading and
the distance from the mains supply.
Emergency/service work
An IP65 Rotary Isolator switch is recommended for
the hot tub to be isolated outdoors in an emergency
or for service work. This is simply a rotary on/off
switch that should be sited more than 2m away from
the hot tub so that individuals cannot be in the hot
tub whilst touching the switch.
PLEASE NOTE
:
Your electrician should leave at least 10m of
spare cable attached to the isolator to reach
the side panel where the control panel is. The
delivery team are qualified to connect this
cable to the inside of the hot tub however
they will NOT hardwire your hot tub to the
isolation switch.
If you are in any doubt at all about the
required electrical guidelines you should
seek professional advice from a fully
qualified electrician.
