6kw sauna heater

6kw sauna heater (post #215633)

Bought heater off eBay and seems very hard to hookup, several electricians  are baffled. Essentially I am trying to hook up the heater to a 220v 3 prong outlet. Here are some photos.

Yes, however, I had another question - do I hook a hot wire to the section labeled "neutral' and one to the "live"

You could have asked this in (post #215633, reply #3 of 10)

You could have asked this in the other thread.  But basically you just do it.  The labeling assumes a 380V 3 phase supply.  You have a 220V/110V 1 phase supply.  So you don't use the neutral in supply cable at all (you'd use it to obtain 110V) and just wire the two "hot" wires to the two input terminals (which are labeled N and L in the diagram).

Oh okay, thanks - so I assume that when I wire this to my 3 prong dryer plug I put the the two wires going out of the heater on the right and left and put the ground attached to the "neutral"

You'd put the incoming neutral (of a 3-prong 220V plug) to the #1 pin on the heater.  It would be better to have a 4-prong plug, but it's probably too much work to change.

You have bigger problems than (post #215633, reply #7 of 10)

You have bigger problems than that . The elements are rated for 220v and you are going to be putting 240 on them so it will be running hotter than they say. You will be running 3 heaters in parallel so the watts will be over 8kw and that is too much for a 30a circuit. Maybe only use 2.

If you look at the diagram on (post #215633, reply #8 of 10)

If you look at the diagram on the bottom, 240V is allowed.

The issue is not whether it (post #215633, reply #9 of 10)

The issue is not whether it is permitted, just what the current it will draw will be.

The resistance of those elements does not change but watts increase as the square of added voltage. You are also going from 3 phases to single phase. It adds up fast.

But you don't know whether (post #215633, reply #10 of 10)

But you don't know whether it's the 1000 watt elements or the 3000 watt elements.  And according to the top line, the elements are speced 230-240 V.
