Title: Power connector for heating element
Post by: MrChalky on May 07, 2014, 12:01:54 PM
I'm planning on getting this (http://www.ebay.co.uk/itm/HE4830-4ft-3000-watt-3-Kilowatt-DRY-ROD-HEATING-ELEMENT-/130404428907?pt=UK_BOI_Restaurant_RL&hash=item1e5cb5ac6b) heating element for my keggle.

My problem is, at 3kW, it needs more than the standard 13A plug, or 10A kettle lead.

I was looking at C21/C22 connectors, (rated for 16A at 155 Celsius), but I can't find them for a reasonable price in any of my usual sources. Anyone know where I can get them? Or perhaps recommend an alternative?

On a similar note, what are the wall sockets normally rated at?

Would I be better off just using 2kW elements?

My budget for the moment only covers 1 of those elements, but I would probably add a second one down the road.

The link wouldn't open for me, I presume that the elements are straight and can be bent into shape?  The norm for this type of element is that 2 holes are drilled quite close together and the contacts pushed through. The cable is connected via spade/lug connectors.the terminals should be enclosed in a box, preferably a metal box due to the heat. The box must be earthed, connect a 2.5 mm heat resistant flex via a heat resisting flex gland.pg 30 I think they are called, and simply connect the cable to a 13 amp plug top. I would highly recommend the MK brand of plug top and socket. 13 amp sockets are rated for 3. Kw however the cheaper brands can struggle, particularly if the socket is unswitched. MK will have no problem, especially if you use the switch to isolate the element before unplugging the plugtop.

I've fixed the link.

Thanks. I'm feeling better about the 3kW element now.

I was hoping to use the connectors so I could remove the cables for transport, but I might just leave that for an upgrade later.
