UK Should I replace a Redhead Fuse Link with Double Pole Isolator?

[ibra123]

Hi Everyone,

I’m currently working on an HMO where the supply cables run from the Ryefield board in the electrical riser to each apartment's utility cupboard.

At present, the armoured cable from the Ryefield board terminates in a Redhead fuse link, and from there, it connects to the consumer unit switch. From what I understand, in the current setup, the Neutral cannot be isolated, as the Redhead fuse link only isolates the Live conductor.

My question is: is this arrangement compliant, or does the Redhead fuse link need to be replaced with a double-pole isolator to ensure both the Live and Neutral conductors can be isolated? I can provide photos of the current installation if needed.

Pulling the main cut out fuse also doesn't isolate the Neutral.

Isn't that why we would normally install a double-pole isolator before the Consumer Unit for maintenance purposes?

Your double pole isolation is at the consumer unit it is fine.

I was thinking more about if the consumer unit needed to be replaced, or if just isolating the Live would be sufficient for the electrician to work on the distribution board?

For a TN system neutral is deemed at earth potential.
