Finally got around to installing 4 x Gigawatt G-16a MCB and one Doepke DFS-2 Audio RCCB, however the job was not as easy as simply replacing like for like in the Hagar consumer unit.

Thankfully the Doepke does meet the same size and shape of the Hagar MCB, with a little adjustment to the length of the exposed tails due to the entries having less depth for the bare wire. Perfect clamping mechanism from the Germans.

The Gigawatt unfortunately have their cable entry points further forward and so do not align with the existing copper busbar or the Doepke cable entry. This necessitated star linking to the Doepke with some spare Oyaide copper cable. The cable entries also have that awful centre screw like Furutech use which I dislike. I presume they expect people to use a spade lug. They are also a touch wider than the Hagar MCBs and fit very awkwardly into my consumer unit and don’t allow the cover to be put back In place. In my music room that doesn’t matter but may invalidate your home insurance cover. You have been warned.

This is not a task for non electricians and I would advise employing a certified electrician to complete the work.

Initial thoughts? They sound a tad dull but understand they require 12 days minimum to open up. Let’s see.

Here’s my current mains setup which has evolved over the years. With hindsight it may have been easier (better?) to have purchased something like a Gigawatt PC-4 Evo and be done.

Posts about Doepke and Gigawatt breakers really piss me off as we cannot get these in the States! I've tried. You ex-Us guys are all very fortunate to be able to access and use these devices!

Blue58,

Are you able to post some photos of your installation please?

This is currently (no pun intended) of interest to me, having looked at the Kemp Electronics website and been suitably tempted.

I have some Henley blocks, tails and a MEM consumer unit with 32A RCBO's from my upgraded installation in my last house. The mains quality is very good in my current 'new-build' home, so I haven't bothered with the mains (but you know how it is!).

Contact mark@wellpleasedav.com for Gigawatt breakers in the U.S. They need to be installed in a subpanel with a dedicated DIN rail in order to be mounted properly. They will not fit into a standard panel.

A bit of a botched job I’m afraid because my panel would only accept 4 breakers max, of Hagar brand, and as the Gigawatt are slightly wider, 0.5mm, the fourth would not clip onto the rail. I had to make adjustments to the cover to enclose all the wiring. And, as stated before, the busbar does not line up so I star wired the 4 breakers into the Doepke.

i think you would be fine with your MEM box if it accepts more than say 6 breakers.

Blue, what's the break in on all this? You've talked about hundreds of hours on SR fuses and the Extreme (thousands?), when do you expect payback on these alterations?

Doepke say 100 hrs (4days) but reported by others to be 12 days. Not sure on the Gigawatt. I think a couple of weeks to a month should be good as they are on 24/7.
Initial assessment is that they do reveal more air around performers and a heavier bass when called for.

But not fully convincing yet? Heavier bass is always a tough call...I mean, who doesn't want "more" bass?
But if that "more" bass ends up as a blunt instrument, then it's a liability.
The biggest reason I turned down Kuraka active isolation, Shun Mook Diamond resonators and IsoAcoustics Gaias spkr footers in my system.
I guess you'll have to weigh up the balance of virtues these changes bring.

I’m convinced.
Didn't say more bass but a heavier bass, just hits harder.
On balance, virtues are all positive.
