Electrical Safety.
Setting up a Green House requires normal care when dealing with electricity such as keeping
cables, plugs and sockets dry and in good order etc. There is the potential to overload circuits.
NOTE: The power requirement of electrical appliances can be found on the electrical
specification label located near the power connector. If it does not specify the wattage it will have
the voltage and current requirements e.g. 110-120 volts and 5 amps. Multiply the voltage by the
current to get the wattage. In the example above 120volts x 5amps = 600watts. If the current is
specified in milliamps instead of amps, divide the result of (Voltage x Amps) by 1000.
Warning: Overload of power outlet can be a serious fire risk
A Domestic electrical circuit can power a total of just over 2000w at 240v / 1800w at 120v.
A small Green House with 1x 1000watt light, fans, a dehumidifier and carbon dioxide, could run
from one mains output. I.e.
Lights 1000Watts
Fans 40Watts
Dehumidifier 300Watts
CO2 Solenoid 10Watts
Harvest-Master 10Watts
--------------
Total 1360Watts
What about a Green House with three 1000Watt lights, fans, a cooling device, a dehumidifier, and
carbon dioxide.
Lights 3000Watts
Fans 40Watts
Dehumidifier 300Watts
Cooling Device 800Watts
CO2 Solenoid 10Watts
Harvest-Master 10Watts
--------------
Total 4160Watts
A total of 4160Watts needs to be distributed over at least two, or preferably 3 electrical circuits
(usually two different wall sockets on different fused circuits). Equipment could be arranged so
that two 1000Watt lights are on different circuits and the rest of the equipment sharing those, or on
the other circuit.
