Your new spa’s GFCI will trip.
A Ground Fault Interrupter (GFCI) Trip Test must occur to
allow proper spa function.
Spas that come with MXBP20 and MXBP501 control sys-
tems come with special instructions for the installer/
electrician. If they have not already advised you on what
to do or expect from the GFCI Trip Test, please contact
them for instructions.
If the GFCI breaker connected to your spa trips, this is
normal behavior. Please reset the breaker and enjoy
your spa. The trip test has been completed successfully.
If your spa was not wired to a GFCI breaker or your
breaker fails the GFCI Trip Test, the spa will repeatedly
attempt (at preset intervals) to trip the breaker in the fu-
ture until such time that it triggers a GFCI Trip. If a GFCI
does not trip properly, your spa’s display will show an
error message.
GFCI breakers are important safety devices required by
code for your hot tub. For more information, refer to the
MXBP20 and MXBP501 sections of this manual or your
local dealer.
