Help With 220v Outlet
1 Attachment(s)
Can anyone help me ID this outlet? I'm looking for a heatstick for my HLT that can heat up 12 gallons to 170 in a reasonable time.

From the google it looks like a nema 6-20 outlet but I don't have any electrical knowledge so I'm not sure.

I would like to buy this heatstick from High Gravity Brewing (http://www.highgravitybrew.com/productcart/pc/Heating-Element-4500-Watt-SS-306p2514.htm) which has a 220v 30A nema 10-30r plug.

Can I just buy an adapter and use it on my 220v nema 6-20 plug? Is it the same amps?

Should I just go with 2 120v heatsticks?

Also I live in an apartment and the building is pre-war which makes me wonder about how good the wiring still is. Idk if they have upgraded it or anything.

That is a 220V 20A receptacle. Probably for a big window unit air conditioner originally.

I use two 1500W elements for 5g. batches. Easily boils 6+gallons with both. Just plug into separate outlets on separate circuits and make sure nothing else runs on those circuits. Also make sure they're GFCI or wire yourself a GFCI box that plugs into them.

you cant go entirely by what the plug looks like, you need to know the size of the wire its hooked up to, and also very importantly the size of the fuse its on.

assumign, though, that its a 20A circuit, the most you will be able to get out of it is about 4500 watts at 240v. that is 18.75 amps.

if its 220v, the max heater you can use is 4000w (18.2A). so it matters the exact voltage, and the fuse rating behind the plug.

Clarification, if it is on a 20a double pole breaker, you can use an element rated for 4500watts @240v. If your actual voltage is 220v, the element no longer functions as 4500w but rather 3781watts. These elements are fixed resistance so a 4500w element is 12.8 ohms and the voltage applied will generate current per ohm's law.

220v / 12.8 ohms = 17.19 amps. 220v * 17.19 amps = 3781 watts.

Yeah I'm just going to go with two 120v heatsticks on separate circuits since I'm obviously in over my head haha. Electricity freaks me out.

Thanks for the replies
