Hi there, i'm a newby here and just looking to confirm a few points with the wiring for a new cooker/hob from the wealth of expertise that seems to inhabit this forum. Just about to start my training for - Part p (defined scope) domestic electrical qualification
I've looked around many similar posts but none seem to match so hopefully you can advise.
Just moved into a flat and replacing kitchen, as part of that a new single oven (to be hard wired & rated at 3.2 - 3.5Kw 13-14A as per the manual), a gas hob and hood are being installed. There is an 30A protected, dedicated radial circuit, fed from a separate fused (not MCB) isolator beside the main CU in 6mm t&e. The cable runs to a 45amp DP cooker switch above the worktop that feeds a 45A CCU below. There is a switched FCU right beside the CCU that I assume is a spur from the CCU as it is isolated when the cooker switch is off.
What I need to check is -
A) The cooker manual asks for a fused DP isolation switch within the fixed wiring but I have never heard of nor can find any rated above 13A - will the existing installation be OK? Even then a 3.5kw draw should surely be covered, by my calculation, by min 15A? (3.5Kw/240V = 14.6A)
B) Is that fact that a FCU has been spurred in 2.5mm from the CCU within the regs given that it's a down stream protected spur under 3m?
C) Depending on the previous answer, the gas hob has electric ignition cable with a fixed plug - I plan to use the FCU that is spurred from the CCU with a 3A fused as per the hob specs, any issue there?
D) I have 25A heat resistant flex to feed the oven from the CCU, anyone see an issue with using that?
E) there is no additional feed that the hood could use, the sockets are separate spurs from the ring therefore could not feed from them, any issue with feeding the hood with another 3A FCU from the radial given the draw on the circuit is well within limits?
Many thanks in advance
Rob
