Dockhead, here in the US when we hear "England" and "electrics" in the same breath, we tend to think "Lucas, the King of Darkness!".

Hopefully your 33L guys do a better job than Lucas did on the sports cars? <G>

Lanor rates are all over the place in the US, the problem with contractors in general and marine contractors even more so, is finding ones who are honest, competent, and actually willing to show up to do the job. A $50/hr electrician and a $125 electrician may be complete equals, the trick is to find a good one at any price.

Escape Plan, you may find a pro will want to do the entire job himself, not unreasonable since that way he can warranty the entire job, but sometimes a bit expensive. It never hurts to ask "What would you be willing to let me do/supply, in order to keep down the overall costs?" And, to give him a precise written list of what you want done, up front. Adding a circuit or two may mean changing a whole panel or buying a whole extra spool of wire--so planning ahead and giving him a clena start would be Job Number One.

Stillraining-Excellent job.
A few fine points:
1. It appears that you have more than one conductor attached to the load side of several of the circuit breakers. I try very hard not to do this and generally will lead a single, typically AWG 10, conductor from the load side of each CB to a terminal strip where I distribute to multiple loads using jumpers on the terminal strip.
2. By combining B- (yellow) conductors on the Ship's Ground, you have made future troubleshooting a bit more difficult.
3. By not labeling the B- (yellow) conductors on the Ship's Ground, you have made future troubleshooting a bit more difficult.
4. By not labeling the Safety Ground (green) conductor on the Safety Ground Bus, you have made future troubleshooting a bit more difficult.
5. Ditto for the neutral conductors on the Neutral Bus.

I do not see the tie between the Safety Ground bus and the Vessel Ground Bus (B-) as required by ABYC Standards.

I don't understand why you have installed to shunts in series. Can you enlighten me?

Overall a great job!

Charlie

Charlie...You are asking the wrong guy these questions...I don't know half of what your asking/telling me...I know enough about electricity to get shocked real well and that's about it.

One shunt is for the Blue sea Panel and one is for the Link Pro..As far as labeling..it is what it is...

I am VERY happy with the work done, how fast it was done and the attitude in which it was done...If the Yard operated the way the sub contracted electrician did I would have been sailing a year ago.

Now..in regards to labeling every wire...is that something I can do fairly easily later?...and is it a continuity check issue for each one to do that?

The yellow and black wire situation. Yellow is the new standard for DC ground wiring B- on a boat so as to differentiate it from the black AC hot wire. You should be able to know immediately that you are looking at a DC ground wire B-. Now when you see a black wire you want to be very careful with it and assume that it is 115 volts AC until you prove that it is a DC B- wire.

As for labeling, you will have to do a continuity check on each wire. But the problem doesn't stop there. There are two wires going into each ring terminal. So, when you do a continuity check you will not know which of the two to label.
