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.

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.

Sounds fine

But you won't get discrimination unless you can get fuse holders to fit the existing board to supply the new board.

see if any two lighting circuits can be put into one breaker

what is that a snakes and ladders ,one circuit only for that .

Davesparks just beat me to it, not a good idea to feed one board from another via an mcb.
It only needs a decent fault on the new board and it could easily trip the whole board.

If I was hard pushed I might be able to find room for a single pole mcb, but not triple pole I'm afraid It would have to be a sub board or new board

tell your customer he needs to pull a golden egg out of duck A77,if that board needs changing .

The OP only needs to install one circuit, if he can gain enough space for an MCB to feed a sub-board he wont need a sub-board!

I think it's rather silly to dismiss the idea of grouping together one or two circuits to gain enough ways, without knowing the loads/circuits involved it may be a perfectly viable option. There seems to be a trend on this forum of late to dismiss common sense solutions to a simple problem as a bodge, and advocate 'walking away' if the client wont pay for the perfect end product. Perfect is not always required as long as a solution is safe, compliant and keeps the customer satisfied.

new 3p circuit to be added

it depends what is the load .

Ah sorry about my post regarding a 13 Amp socket reread your post and it's a new 3 phase circuit that is required sorry if I confused the issue, my bad.

No sh#t Sherlock.

Agree,& that may be the logical way to go,I doubt very much the client is gonna be happy with the idea of a new Db & costs.
If we walk away from it,no doubt someone will do it.
All will be noted on the certificate,so will pass the onus back onto the customer.

well said tooth puller ,I could not say better me self.

Is that a different orifice to the duck's A55?

Client refuses............SEE YA

Not always, a very blinkered and unprofessional approach to only see one solution to a very simple problem.
