[FONT="][/FONT][FONT="]Hi, someone wants an electric hob of rating 6Kw fitted in a static home thats feed by a 40a MCB there is one 32a ring final, two 6a lighting and one 16a oven circuit, after applying diversity the installation is already over its maximum demand a little without adding the hob.[/FONT]
[FONT="] [/FONT]
[FONT="]It is unlikely that they will use anywhere near full 32a of their ring final and more than 2 burners of their hob and their 2.35kw electric oven at full power.[/FONT]
[FONT="] [/FONT]
[FONT="]The hob and oven are likely to draw 17 amps on average if used together as a guess plus the kettle on the ring momentarily adds the additional 13a this equates to a load of 30a.[/FONT]
[FONT="] [/FONT]
[FONT="]Lights after 66% diversity are 3.96a each but more likely will draw under 1a on average.[/FONT]
[FONT="] [/FONT]
[FONT="]Leaving just about 8a safety margin roughly, without the 32a ring added but again the regs don’t allow diversity on the first ring final.[/FONT]
[FONT="] [/FONT]
[FONT="]The owner has had 2 sparkys round already and both did not give a definite answer. Can someone please sled some light on this.[/FONT]
