Interlocked sockets

Neil1980 over 5 years ago

Hi all.

Recently had a contractor carry out a periodic inspection on our site (warehousing and workshops) and they have specified that all the 16A and 32A (1ph & 3ph) sockets need to be interlocked.

Is this true, or are they just finding £5k of additional work to carry out?

I can only find reference to caravan sites (Sec. 708) requiring interlocked sockets.

Any other sections that reference this requirement on industrial and commercial installations?

Thanks in advance,

Neil

Thanks for the additional information, Andrew.

This makes sense and highlighting Table 537.4 definitively highlights the situation with regard to isolation and functional switching.

None of these outlets are over 32A, so fine for Isolation and Functional Switching.

Still can't find any references to interlocks other than Section 708 and electric vehicle charging.

Thanks again,

Neil
