The current draw is approximately 0.1A for the solar controller
and 0.8A for the gas continuous flow water heater. If a new
power outlet is to be installed and wired to an existing power
circuit, consideration should be given to how many outlets
are already on the circuit and if the existing cable is capable
of handling the added current draw of the hot water system
or any other appliances that may potentially be plugged into
the new outlet. If a new cable supplying the outlet is to be
installed, it shall be protected by a suitably rated and labelled
circuit breaker. It is recommended that the outlet be used by
the hot water system only and not be shared with any other
appliances.
Electrical installation
The solar hot water system is required to be installed in
accordance with the AS/NZS 3000 wiring rules, the local
electrical authority regulations and any other applicable
standards. The pipe work, storage tank and collectors are to
be properly connected to the earthing system of the premises
in accordance with AS/NZS 3000.
Means for disconnection must be incorporated in the fixed
wiring in accordance with the wiring rules. The insulation of the
fixed wiring must be protected by insulating sleeving having
an appropriate temperature rating.
The solar controller and gas continuous flow water heater (if
system is gas boosted) require a weatherproof socket outlet
with a 240 volt alternating current continuous power supply.
This outlet shall be located as close as possible to the hot
water system, ideally within one and a half meters of the solar
controller and gas continuous flow water heater (if installed).
