Wiring In A Sedgwick Planer

[woodworkerdicky]

I have just purchased a secondhand planer and need to wire in a 16 amp socket with a 32 amp breaker using 4.00mm2 wire, this is all specified in the manual. The motor is a 1.5KW single phase, the manfactures give the full load as 9,00Amps and the starting current as 56amps. I don't understand how you can have a 32 Amp circuit breaker and expect to get 56Amps through it to start up the motor? Also I have found a GE breaker BPCV which is 30mA which again I don't understand, so I am not sure if this will cope with the motor or not?

Can someone give me some advice please.

Many thanks

a 16a socket must be protected by a MCB of 20a max. 32a is non-compliant & the manual really does say that, then i would complaint about it. if it really needs to be 32a then you will need a 32a socket & 32a mcb

motors always use more power on start up. its normal and only for a very short time so not really a problem with smaller motors

the breaker you have found is an RCD and not suitable for overload protection

also, if this planer is for commercial / business use then you are not competent to be doing this. if its home / DIY then your still not competent, but hopefully its only you that it can affect / kill if it goes wrong

A 20A   C type MCB/breaker would probably the my choice on the info supplied,

but, you need to ensure your Zs / earth is adequate for this to be suitable.

Hi, I have just phoned the company and they have amended their operating instructions in the new mannual now for the breaker to be 25Amps and to use 2.5mm cable. Does this now make sense its not as you suggested but is that OK or still not right? The machine is for my garage, I have used planers for 30 years up to 2hp, but this is just that little bit more powerful and needs some upgraded electronics. I am just trying to find out what is required, I have had lots of conflicting advice from various sources and manufacturers are afraid to advise on anything other than whats in the manual.

25a cannot be used to protect a 16a socket. regs clearly state 20a max. there is no more to it than that.

your best option is to call a sparky to look at the job and he will be able to decide what size circuit is required

Looks like another word in the shell like @ Sedgewick is needed, AGAIN!

Getting fed up with this now.

I have even offered to do the calcs and re-write the manuals for them, but Oliver says it's OK!
