A single 1000 watt magnetic/coil ballast draws 4.2 amps at 240 volts, so by plugging two 1000 watt HID lights into a wall outlet in locales that use 240 volts this would mean you were drawing 8.4 amps giving you plenty of room for safety right? The circuit box and breaker that supports the outlet may be inadequate to handle the increased electrical load. The wiring and/or the outlet might be old, damaged, frayed, shorted, or otherwise compromised. There are several things that can be problematic. However, in most cases the wall outlet is ill-equipped to handle the electrical load. They plug lights, fans, air conditioners and other high-load electrical devices into a wall outlet. Just one problem is that many growers set up their grow in a closet or a bedroom. In either instance, you lose a secure place to locate your grow when all of this could have been avoided. At best, should your house not burn down completely, a shed or house fire will undoubtedly result in eviction for renters and a compromised grow for home owners.Additionally, large fines will be incurred for any illegal wiring. Should your house or shed catch fire, your house will be subject to a costly electrical inspection and repairs/upgrades if any non-compliant wiring is found.Further, if you have overloaded power points and/or extension leads beyond their designated maximum load your insurance company will not pay for damages.
Your house & contents insurance policy will not cover fire resulting from unlicensed electrical works in a room used to grow in. It doesn’t matter how stealth your grow is if it catches fire, your grow will be found Nothing will bring the emergency services to you house and your growroom like a fire. were directly attributed to electrical bypasses and lights associated with hydroponic operations.” were caused by grow operations or drug labs, resulting in two deaths, 26 injuries and more than $16 million in damage.įrom 2005 to 2009, 136 fires across B.C. Too often indoor growers fail to understand this and in some cases this ends in disaster.įor example, it is all too common to hear of house or shed fires as a result of indoor grows going up in flames.Ī 2010 working paper from British Columbia notes a home with a grow operation is 24 times more likely to catch fire than a typical home. This often means that standard house wiring is inadequate for powering indoor grows. This means that when a house is built, the wiring which is installed is done so with domestic purposes in mind. The problem is that most houses are wired for domestic, not industrial, purposes. Many growers run a lot of HID lights which creates an extremely heavy power/amp/watt draw on electrical cables. The reality is that a growroom, for lack of a better term, is an ‘industrial application’ which is configured using lighting and other equipment that was designed originally for industrial purposes. This is area of the utmost concern, but a factor that is far too commonly overlooked. Any electrical work should be conducted by a licensed professional and wiring should be compliant to safety standards within your locale.Īn extremely important issue that all indoor gardeners need to consider when designing and implementing their growroom is electrical safety. The following material discusses electrical standards (cable size, amperage ratings etc) in 240 volt situations. In Australia, 240 volts is the standard and cable is measured in mm. For example in the US, 120 volt is the standard with 220 volts for larger appliances and cable is measured in gauge. Note on Electrical Safety: Different voltage and safety standards exist in different locales.
