Wiring heaters together

Postby bgagurl » Sun Jan 25, 2015 2:21 am

I wanted to update t8280 and was considering using 3 or 4 heaters

I had planned on wiring them in series and wasnt sure if that would work properly and that is should do parallel

What T8280 machine do you have? Older one with four narrow plates? Or later style with two larger plates? Is yours 220v or 110v
machine? Plates are always hooked parallel originally in any machine you buy. If you have a have two 220v elements and hook
them up in series rather than parallel, it will cut the wattage in half. But two 110v elements hooked in series and powered by
220v will operate at their designed voltage and wattage. You making a new enclosure? Don't see how an 8280 would fit more
plates.

I have the model with 2 plates, and its 220v i was going to put either 3 or 4 heaters instead

Yes originally it is parallel but since im putting more in, series looked simpler to do

If i use 2 110v elements on 220v wont that cause them to blow?

If i understand, series causes power loss, parallel allows full power?

Think of your heating elements as very high wattage resistors, because basically that is what they are. Two equal resistance plates
hooked in series to 220 would result in each plate getting 110v. I just wondered if you had 110v plates cuz you mentioned hooking up
plates in series. Sounds like you haven't attained the extra plates yet. Just buy the 220v plates and keep all plates hooked up in series.
Hooking any of them up in series will drastically cut voltage to your plates. For example: If you had four 600w/220v plates and hooked
them all up in one long series, you would get a whopping 150w of power from all four plates combined. Parallel gives you 2400w.

We use parallel in most of our machines, we were considering series but decided against it for obvious reasons

We mainly work with 220v so i guess i will just get another ceramic terminal block and wire them the default way

Thanks, quite useful information for our next project SMT machine

Picture explains better. If you apply appropriate voltage to 110v element, it will perform the same as if were in 110v machine.

Is B the shared Neutral for both circuits A & C?

Yes i am using 220v so i guess i will just get a terminal block and wire them

So how is Ace doing? He moved and is still doing repairs?

No. They don't use Neutral in US 220v circuit. They use two 110v lines. In rest of world besides Canada, they use Neutral and a 220v line
for everything.

That makes total sense, i did some google searching on series versus parallel and basically the information you provided just cleared it for me
