Adding circuits to a full DB

[cliffed]

what's your take on adding circuits to a full DB.
Warehouse unit,3p DB,full to capacity,new 3p circuit to be added,client refuses to upgrade DB.
Would you reconfigure a couple of circuits to allow for this new circuit.

 

[Pete999]

No I wouldn't. not unless there was a single 13Amps socket that you could spur from an existing 32Amp RFC.

 

[GMES]

No, tell him to get his hand in his pocket.

It is possible you may be able to ditch some if they serve no purpose but otherwise they need to shell out.

New board next to it fed from the existong would be his cheapest option

see if any two lighting circuits can be put into one breaker. sometimes the lighting circuits are split for convenience e.g upstairs and downstairs and it isn't always unsafe to put them into the same breaker. otherwise just tell him you want to do the job properly and if they arent prepared to pay for it then run away

Agree,thanks

Yea that’s the best option,will need to switch off & reconnect tails etc.
He’s not gonna be happy,work will either be @ night or weekend.

When he expresses his disgust with shutting down his site for works perhaps remind him that doing it properly this time round and installing a DB with many spare ways will prevent this problem from happening again in the future.

Edit:

Another option could be to consolidate a few 1P circuits into their own DB fed from the exsisting 3P DB. You could move 4 lighting circuits over to a 1P DB and have enough ways for a 3P MCB and 32A SP MCB to feed the new DB.

You are going to lash a new board off the live side of the existing one??

No..connector blocks to supply new Db

If you’re doubling up a couple of lighting circuits here and there, and maybe a single point spur onto a ring.... you’re going to have to reconfigure a lot of other circuits to get 3 together for a 3 phase circuit.

No bodge job, @cliffed Tell him it needs to be done right. Got to keep those phases balanced and all that.

Agree,hopefully go for the new Db

Yea,he’s gonna have to go with the flow.

Sub board off the existing board for me, not a henley block. Then move a few circuits over to the new board to make way for the submain breaker.
