Even fitting a cooker makes us think. Well done mate for being a good honest sparky. Some electrician's would have gone to town sensing her concerns that install
Silly question but...why don't you are using 3-phase system in houses? For flat cookers (mostly in central europe), we are using breaker 3x16A (3x10A sometimes enough too) and 5x2,5 cabel. Easier work with thinner wires and in my opinion, more power for anything.
4mm is rated for 32 continuous (assuming reference method c, no derating factors), technically the 4mm flex at the cooker would handle 41 amps as in free air but not a good idea behind a cooker. the circuit only extends to the outlet plate so no modification to the circuit occurs, its just an apliance so no need to add rcd protection.
@@conorlanders8401 - A '6mm for cooker circuit' is a throw back from the old BS3036 30A rewireable fuse days when a derating factor of 0.725 was applied so a 4mm cable was not permitted as it took the cable rating below the fuse rating. The next size up is 6mm (IM C).👍
I did one recently for £20 with 6mm t and e client bought. Took 2 hours with testing as cooker plate was old and 'threaded' and cooker had cheap connections which could fall apart with ease and link plates. Nightmare. £80 a proper quote but you think 20 minute job....duh
Only single phase connection on the cooker? Interesting. Can't say I've seen that before. They usually have three phase with copper bridging if you want single phase. We call it a stove or stove and oven in South Africa just FYI. Maybe a hob if the are split units. The big tank water heater we call a geyser. No idea why. Only used for plumbing purposes (bath, shower, basins) and not central heating. Central heating is not a normal thing here.
@@alex_lightning4523 Yeah but do you actually get a lot of cookers specifically manufactured for the UK market? I thought most of them were common European versions that came with little copper jumpers for all sorts of supplies (1ph 230 V, 2ph+N 230/400 V (i.e. two out of the three phases from a 3-phase supply), 3ph 133/230 V and 3ph 230/400 V, even 230 V 1ph 2L+2N (i.e. two single-phase circuits)).
I came to see the full installation of the cooker and you didn't even show connecting the cables to the cooker and to the box. Just irrelevant chit chat and a before and after shot. Yeah great stuff. Video not fit for purpose really.
6.0mm t/e cable can only be protected by 40 amp MCB if it is clipped direct. Hope it’s not in thermally insulated wall. Also, you ran a new cable to the cooker and didn’t connect it to RCD protected side of consumer unit? If the cable is buried in a wall less than 50mm depth, RCD protection is required. Reg 522.6.101
as far as i could see he only changed the flex to the cooker, the outlet plate is the end of the fixed wiring which would fall under the requirement for rcd protection.
