CU change...is it ok to keep old ELCB as an isolator?

[bleach]

Hi chaps

Is it acceptable to just keep this ELCB in place but as an isolator? or should I get rid?

Thanks

IMO, it's acceptable, but for what it costs, i would replace with a 100A D/P isolator. you don't know if the internals of that VOELCB are in decent condition.

cost both options with recommendations to customer to change

If it is a VOELCB I would replace it with a DP switch

Ok thanks

could it not be removed if a new CU is fitted?
a DP isolator wouldn't be required

True...but I do like an isolator upfront for future work. Just my preference.

there's one in the CU

Can't really see a problem with leaving it in place as a DP isolator, but do remove the earth conductors from the unit!! If the truth be know the Switch, contacts and mechanism, is a dammed sight better engineered than those of a new DP isolator!! lol!!

Ask yourself why an isolator before the CU would be beneficial, especially when contemplating a CU change!!

if its less than 3 metres and your changing anyway, just throw it into the CU

I might use this one for my NAPIT assessment... Would the assessor frown upon this being left in place as an isolator? eg... is it still recognised or is it well outdated?
