My wife has a 3.6 KW kiln with standard plug. It is however around 15 A and I have noticed the standard socket I use has started to go brown. I understand therefore I need a dedicated circuit for it. The kiln is in a attached garage which was converted into double study. Study is now a workshop. I have a fairly old consumer board which I hopefully don't have to change. Any idea what the cost would be. I understand the kiln can be hard wired into the new circuit.
Ah. OK hold on a moment The genie estimates that it will about the same as the cost of an evening out. Could be an evening down the pub. Could be an evening at La Gavroche with bottles of Domaine Ramonet Montrachet Grand Cru. It depends on so many things. You will need a registered electrician - as it is the addition of a new circuit and notifiable. Find a couple of local sparkies and get some quotes.
Depends on many factors not least of which are the ease with which suitable cable can be routed and if the CU can take the new circuit. I would guess 1 or 2 days labour plus materials depending if existing CU can take new circuit or not. So £350 to £700 at a guess. And I am guessing. Just plucked numbers out of thin air.
1-2 days labour If the CU is in the garage, or close by, or you're in a bungalow, it's a couple hours max.
You have probably realised by now that this is not a straight forward job. We know nothing of your installation as it currently stands, sub main cable size, protection used or length of run. It may be that an additional 16A commando plug can be fitted as an exclusive circuit from the existing board, or a 20A DP switch on a similar circuit. The electrician could find that the sub main cable is too small, the CCU has no spare ways, or the original installation simply does not meet standards. Bazza has the best idea, look into the crystal ball, or get some quotes.
Why not? Having a plug designed to BS1363 may be wrong and should not be fitted, but it can have a Commando type plug rated at 32 A (or maybe even 16A) fitted.
