I only have one plug in outlet in my garage running my 220g and want to run my 300g off of the same outlet. Is this possible without tripping a circuit? Any electricians in the house that can advise or members running more than one tank off the same plug in? I don't want to trip the cirtuit breaker because with the tanks in the garage, it may go unoticed for up to 24 hours.

List of equipment:
x3 FX5
x2 PCX40 pumps
x2 T5HO lights
x4 heaters (400w each)
x2 powerheads
x2 airpumps
x2 UV sterilizers (18w & 40w)
 
A 15 Amp breaker can legally run 1320 Watts (maybe it was 1380)...

A 20 Amp breaker can legally run 1800 Watts...


So add everything up and decide what the maximum wattage used at one time will be...

Lights, heaters and some other things will not be used 24/7... but calculate tha max that might be on at any one time.

For example... if you have a 15 Amp breaker... and you have 1,000 W of lights and 1,000 W of heaters... Even though it will be rare that everything is on at the same time, since it will be possible for everything to be on at the same time, you will not want to plug them into the same circuit...

Keep in mind that multiple outlets will be wired into a single circuit/breaker...


When pushing the envelope on this sort of thing it's best to educate yourself on what's safe and evaluate what you have running. Your 300 gal won't be any fun if you burn the house down trying to facilitate it...
 
I'm not an electrician. But....

I don't think you can do it. Even with two power strips you wouldn't have enough plugs. Probably risking a fire.
You should look into having an electrician install a sub panel in the garage and give you a bunch of outlets. Then you will have room for expansion and be safe.
 
Is it a finished garage? You need to know what amp circuit your going to plug the aquariums on and if there are any more outlets that share that same line. If the garage is unfinished then I would just run a dedicated line for the aquarium and then not have to worry about the circuit being tripped. Would need to know the amp load on your equipment.
 
I always appreciate your reaponses NC ;) thank you. I am having a hard time finding the actual or highest wattage of each of the pieces of equipment I listed above. Gut feel, would it be pushing it? I don't want my place to burn down either...

The garage is finished and my landlord will not respond if I can have an electrician install anything or not. :(

I am sorry for being such a tool but how do I tell how many amps and watts a plug in is? Nothing on the panel says "garage" but there is on with a 15 on the switch marked "GFCI plugs" the rest say bedroom, range, dryer etc... Does that help? Can I assume the 15 is the amps? There are 20 and 40 (range) on the panel as well.

youll be fine i run my fan, my computer, 48inch tv, drum amp, ungraded speakers for my computer off one outlet.

on my other i run 3 300 watt heaters 2 eheim 2217, 2 hob, air pump, 4 8ft lights, 2 18inch fans.
 
To say if it's doable or not depends on the electrical installation you actually have. What is the gauge of the electric wires placed in the single AC outlet?

If this single outlet is the only one wired in the circuit, then figuring out what your upper limit might be is easy. If not consider disconnecting other outlets and keep this one as solo in the circuit. I rather use volts-amperes but you could use any variable you like as long as you use only one (e.g. don't add up watts/hour with watts).

How much energy is your system needing? The most accurate way of finding out would be using an ampere meter (usually a clip-on instrument, you place the hot wire inside the clip and read). You could also just use the data provided by the manufacturer of each piece of equipment if you trust them.

A 14 gauge cooper wire insulated for say 90 Celsius is likely to handle up to 30 amperes but for security reasons it usually goes with a 15 amp circuit braker. There are some losses that need to be addressed, like loss of voltage due to wire length, temperature, quality of connectors...

Consider adding up the wattage of all lamps, then the wattage of all pumps, the wattage of chiller/heater (if used) then the wattage of all airpumps and whatever other accessory that uses electricity. For safety reasons, I consider all my tanks as somewhat inefficient systems, with a 0.75 power factor. That is if I have 10W of lights, the actual energy I need to lit that lamp is 12.5W. In other words add 25% to all listed consumption.

The final number would let you know where you are standing.

If your numbers fall within reasonably safe range, then you could use as much strips as you need for wiring your tanks needs. Be certain to follow security guidelines to avoid or minimize fire risk.

two outlets with two breakers. between those two breakers i have 2 eheim proII, 2 AC110, timer and light, heater, airpump and two powerheads.
