Rev Posted September 9, 2004 I need to buy a second sterilising unit i need hel to figure out if i can run a particular model on a home circuit and/ or what details i need to know, look for so i can find out Item All american 75X electric steam steriiser from mycosupply.com specs 1349 Cubic Inches 41.5 Quart Liquid Capacity 120 Volt 50/60 Hz, 1650 Watts/13.75 Amps - - - Or - - - 240 Volt 50/60 Hz, 1650 Watts/6.88 Amps Info from fungi.com "NEW! The 75X 41 Quart Electric Steroclave Anticipated for years, available at long last! This is the ultimate tabletop media sterilizer for the professional cultivator. The huge 1349 cubic inch capacity is sufficient to hold up to 15 quart jars, 7 half-gallon jars, 3 one-gallon jars (with room left over for 1 half-gallon jar) or 6 six-pound Sterile Airflow Spawn Bags (SABs). Features a built-in thermostat, indicator light and grounded 3-prong cord. Comes with removable solid insert basket. UL Listed. Please Note: this unit consumes 1650 watts/13.75 amps at 120V. A standard home electrical circuit—not outlet, but an entire circuit—has a capacity of 20 amps. Use caution when connecting the 75X to your electrical outlet(s)." The bold bit is the bit that concerns me! my current a/c's specs are..... Voltage: 240V Electrical power : 2.0 KW does this mean i just have to run them alternately with little else running in the house at the same time? or since im on 240V can i run them both o/night while power usage is o/wise low Im ready to buy but dont want something thats going to cause grief also whats 1349 cubic inches/41.5 qts in litres? is it 39L? or 22L? its the larger model of the 25X The All American 25X Steroclave (pictured above) is a portable electric automatic steroclave. A complete self-contained sterilizer with an immersion heating element, automatic thermostatic control, automatic release valve, and pilot light.

The 25X is a self-contained, gasketless 25-quart pressure sterilizer, complete with electrical heating element, thermostat and indicator light. Popular with cultivators, medical experts and laboratories worldwide. 25X (25 Qt, holds seven 1-quart jars) Ill post on my experiences importing.... and if anyone wins lotto and feels generous you can get me this Quick-Opening Autoclaves (Retorts) Our line of autoclaves cost far below those of most manufacturers. They are constructed of 1/4 inch carbon steel, complete with safety blowouts, quick-opening "spider" doors, and push-in carts. Horizontally and vertically configured autoclaves are available with the option of one or two doors. Recommended operating steam pressure is 15-30 psi. From 4 feet to 30 feet long, from 4.5 feet to 5 feet in diameter, these customized autoclaves make spawn, substrate and/or canning commercially feasible. Preferred by North American mushroom cultivators, each autoclave we sell is custom manufactured to meet the specific needs of our customers. Available for shipment worldwide.

Guest electro Posted September 9, 2004 higher voltage means you need less amperage for the same wattage ... voltage, amperage, resistance and wattage are all relative to eachother .... ohms law told me so with 240 volts you will need 6.875 amps to get 1650 watts accordint to the law .... this is still chunky .. id rec comend using it on a seperate circuit unless you want your lights to dim whe n it kicks in (like if you put an aircon on the main house circiut you will get slight power drops when the compressor kicks in - come to think of it i think my crappy little aircon unit uses 1550 watts heating and 1660 heating 240 volts - it is on my light circuit, seperate to my powerpoints [which is good coz i dont want power surges going thru all my expensive electrical equipment !]) Share this post Link to post Share on other sites
Guest electro Posted September 9, 2004 also conversion tables http://www.planet-stuff.freeserve.co.uk/St...sion_Tables.htm another ref http://www.simetric.co.uk/si_ppm.htm "1 litre of water = 1,000 cubic centimetres (cc) " SO 1349 cubic inches = 22843.57 cubic cm (/1000 to get litres) =22.84 litres if this is a pressure cooker you are so cooking me some grain bags ! lol 20 litre bags at once !

Torsten Posted September 9, 2004 this unit uses about the same as your aircon. prolly about the same as your heater too. you can put up to 3600W on an aussie circuit, however, most powerpoints will get hot at anythign over 2400. Hence these days most heaters are rated at 1600-1800W to prevent extension leads melting etc. It also means you can have two such appliances on one circuit without blowing the fuse. Don't run it on the same circuit as your heater, aircon, flowhood or autoclave - at least not for extended periods. Share this post Link to post Share on other sites
planthelper Posted September 9, 2004 if using extension cords, only get the "fat & expensive ones" simple as that, they simply let more juice thru... watch out that the cords and connective points are never worn down!! sucking 2000 watts thru thin wireing could cause fires and damage to your tools! aswell never leave the maybe too long extension cord wrapped in tight circles or so, straighten the cords or better allway's use a as short as possible cord!

mescalito Posted September 9, 2004 Domestic power circuits for GPO's(general purpose outlets)are normally rated at 10amps,light circuits at 8amps.But bear in mind as you add appliances to the grid it increases the load(current flow)on that particular circuit.Since you're only drawing ~7amps you should be sweet Electro...the running current of your AC is under the circuit rating yes,but unless the compressor is an inverter type,then the starting current, though it is a short burst,can be 20 times the running current or around 120amps-that's a big no-no.The cable on the circuit is prolly 10a rated anyway so be careful they don't melt in the summer because ambient temps 'de-rate' a cables current carrying ability.Then the cable itself becomes a heater LOL Dedicated circuits work best for compressors as they have to push the piston against the static pressure of the gas in the cylinder head on start-up,that's when the amp meter goes off the scale Share this post Link to post Share on other sites
reshroomED Posted September 9, 2004 GPO's (wall-mounted power points) are rated @ 10A and should never have more running through them. Several of these will be connected in one circuit, and guarded by a fuse/breaker usually rated at about 20A. Even though each GPO can safely handle 10A, having two supplying 10A each will trip the breaker. Also, running devices at their max rating is not too clever to start with. You need to look at the total power consumption of the circuit that you'll be using and ensure that it doesn't exceed the rating of the fuse/breaker. That being said, at 7A you should be fine to just plug her in. As a side-note, Ohms Law can be a little misleading here (although not in rev's case). Many electrical devices require much more energy to start than they do to run, ie. motors, HID/flourescent lights, etc. When initially turned on, a large surge of current is pulled by the device, often many times it's rated running current. ANY ELECTRICAL FIXTURE THAT GETS HOT IS DANGEROUS. This means that either the device is failing or that it's operating under conditions that it is not suited to. And this means that a shock/fire hazard exists. It should be replaced immediately, and if the replacement heats up too, call a sparky. Electro, having an aircon on a lighting circuit is far from good. I'd strongly suggest having this looked at by a professional. Pm me for more. Good advice from planthelper, fat and expensive is the way to go. Another tip, when buying audio amps go for the heaviest. ed Share this post Link to post Share on other sites
Guest electro Posted September 9, 2004 re "Electro, having an aircon on a lighting circuit is far from good. I'd strongly suggest having this looked at by a professional. Pm me for more." thanks for the suggestion, but really im moving soon and dont care what the next peeps do - i will get my uncle ( a sparky) to check that it is safe though - mind you ive ben running the thing almost constantly for 3 years now without problems.... the whole house is one big builders shortcut & it wouldnt surprise me if the whole thing is not standing in 3 years ..
