Read before proceeding:
• There must be a circuit breaker or fuse for every toilet.
• For marine applications, follow ABYC guidelines.
• For RV applications, refer to ANSI/RVIA LV and NFPA70/NEC standards (U.S.A.)
or CEC I and II standards (Canada) for the recommended wire gauge. Refer to ”1.3
Supplemental directives” on page 3.
• Use tinned, stranded copper wire.
• Use crimp-type wire connections. Do not use wire nuts, as wire nuts can corrode.
5.3 Planning the electrical connections

remain dry.
