Why not put a receptacle on one side of the toolbox? Then cut the tab in the middle of the receptacles two outlets and have each outlet of the receptacle be on its own circuit. Then just put a plug on the end of your RIMS element and have both a pump and RIMS with plugs. Wire the first RIMS element outlet to an SSR that is in parallel with a second SSR that is powering the pump outlet. That way you can just plug your RIMS element and pump into each outlet and not ruin the pump's nice cord.

That'll allow you more flexibility in the future with your pump and also allow you to unplug and neatly wrap up your RIMS when not in use and have it stored out of sight.

That means I would need to purchase an additional SSR and Heatsink just for the pump? I wouldn't be able to have them on the same circuit?

For those of you that have built this. Are you running both the pump and the element on the same circuit? and is that circuit 240 or 120. If 120 are you using a 15 amp circuit or a 20 am circuit? if 15 amp have you had any problems? tripping breakers and the like?

The short answer is yes. The long answer is no, but you must ensure that your receptacle and SSR that you choose are rated high enough for the load.

The reason I quickly said you wouldn't be able to have them on the same circuit was that pumps, when first turned on, have a much higher current draw to overcome being at rest, which quickly spikes down to normal operating current. That spike of energy has the potential to fry electronics so just be aware of that. However, if you're comfortable with that, then by all means put them on one receptacle with only one SSR.

That being said, let's take an example: If you choose to operate your RIMS on 120VAC and your heater element is the popular 1500 Watt version, then your circuit should be sized like this:

1500W/120VAC = 12.5 Amps
Typical March 809 Pump draws 1.4 Amps on 120VAC (look here for March Pump electrical req'ts)
Total = 13.9 Amps * 1.25 (25% Overcurrent Protection) = 17.375 Amps

Just be careful and make sure to buy plugs, receptacles, etc. rated for the next higher common amperage size, which will be 20 Amps. A lot of commonly found electrical components at places like Home Depot are default rated for 15 Amps, so just make sure to pay attention and grab the 20 Amp or greater rated ones. For your SSR, I would size it for 30 Amps and then you'll not necessarily need to buy a heatsink, as the 17.4 Amps needed to run this circuit is well below the 30 Amp capability of your SSR and it should therefore not heat up all that much. Hope this helps.

I'm running mine on a 120w and a 15 amp breaker. That's the pump and the element and I have my beer fridge on the same circuit with no problems. Cheers

Thanks. what wattage is your element?

1000 watt. It works well but I'm going to try a 1500 soon.

That's exactly what I wanted to operate my RIMS at. I will get a 40A SSR and get the heatsink just in case.

Should I add that 15A breaker to my parts list too? I want to be as safe as possible since I have no prior electrical experience.

Thanks.

Man this project is going to be expensive. $153 for the RIMS tube and fittings after shipping. I still need to buy quick disconnects for it too! :/

you dont need a SSR on a pump, that would be a waste of money, it is an on or off unit. The SSR is because you are cycling the heating element off and on constantly.
