DB installed connected & tested

[cliffed]

Just your thoughts on this DB,it’s a Lewden type,I personally don’t like them.
Bus bar,not ideal,main switch on right,space very tight to make connections,hate the rcbo’s,screws in front of each other,making it hard to retighten .

you call that tight? wait till you try a schneider easy9.

I don't mind them for the money...my preference is hager but the lewden boards are my go to if there's a budget.

If there wasn't so much slack or the slack was dressed a little better then IMO it would make an easier job.

My issue with the Lewden boards is the advised torque settings, I have two torque drivers and with either if I torque them to manufacturers settings it has a tendency to damage the rcbo screws.

Why is the up front RCD not time delayed?

 

[telectrix]

TT?

Agree with torque settings for screws.
Also I hate the main switch isolator on the right, much prefer left.
Anyone know why some boards have the main switch on the right?

Is it a TT system?
Just curious.

Two posts beat me to the answer before I asked the question. TT

most boards have MS on the right. only one i've seen with it on the left is MK.

It’s a 100 ma time delay

Yea it’s a tt system

I like them, quite well made.

Don’t you think the bus bar system ,a bit dated,rather have the plug & play,like Schneider.

I didn't notice the upfront RCD, that's going to be a PITA for the customer in the event of a fault.

@Leesparkykent its a time delayed one so "should" be ok, you can just see the S on the front of it.... The rcbos are only single pole though so there still isnt perfect discrimination and a fault remaining on the neutral will trip the whole supply... Not a great setup imo...

Yes that was exactly my point. Neutral earth fault and the RCBO will trip but the upfront RCD, time delayed or not will still trip as the RCBO's don't break the neutral.

Good point,they are usually supplied with earths,to solve that problem
