three phase kiln

[qwirkyglass]

hi all,

i am trying to do some research for a business plan and was hoping that someone could help.
I have a 3 phase laser kiln, that can be fitted to a domestic cooker plug, as that is what it used to be wired in to.
But i was wondering if anyone else has a similar set up kiln, and if so how much does it cost to run a simple full fuse programme for bullseye?

thanks in advance

I could be wrong, but I think you'd need a phase convertor to run a 3-phase unit on a normal household circuit. Most household electricity supplies are single phase... I would definitely ask an electrician about that. But, assuming you get it connected correctly I think you should be able to run a basic full fuse programme with a medium sized kiln for under a £1 - difficult to tell without knowing more about the kiln in question...

I also thought that 3phase was not suitable for domestic use .......

HI It is possible to run three phase on a domestic supply with some clever wireing, however this msut be done by a qualified electrician
as it could impact on house insurance and that is not good.

I asked the electronics guys at work about this a while ago. They said you only get problems trying to run 3-phase equipment on a single phase supply when a motor is involved. As you already know, you can run a kiln quite happily, but you will get some loss of power.

I don't know how this will affect cost per firing. I think the easiest way to find out would be connect it up and run it through a simple plug-in power meter. I got one from Maplin's for about a tenner.

in our hobbyfuser which runs off a 3 pin plug, a full fuse of a 35 cm dish uses 7 - 8 kw and a slump uses just a bit less.
