Yes they were aware of the rules but by waiting for an ambulance it was going to around two to three hours

Sadly two competent officers have resign because of a formal warning, because they took a injured man to hospital. all of that experience and expertise has been lost.

It was not because they did nor what for a ambulance but because they used a stretcher in a private vehicle

Another vote for Pete.

The person who works from his narrow boat could have the same qualifications as using someone from a boat yard Over heads will be slightly less. A small example public liability insurance is over £ 1000.00 per year.

Most boat yards and individual technician will be charging around £ 60.00 per hour. As an individual I feel this to be a fair price for my skill and knowledge.

You could try Key Diesel from Burton-on-Trent

Is the breaker you are using design for an AC circuit or a DC circuit?

The IET recommend H07 RNF for marine applications. And before anyone starts I am fully aware that at the moment the IET has no jurisdictions.

I was at an installation yesterday which has a BMV 700 & 712 installed, both will not be operational for some time yet, However, I look at both manuals and they give the impression that the 712 has an internal buzzer. I would now talk to the supplier?

Having now read the manual. I will also check on Monday, I am working on an installation which is using a BMV 712 If the buzzer has been activated and all the setting is correct it may be an issue with the monitor itself. I would suggest talking to the supplier

Just taken this from an advert my feeling is it only comes with a contact an external buzzer is required Victron BMV712 Smart battery monitor kit complete with shunt & connection kit - c/w low battery alarm contact. 9-90vdc

Do you not use an external buzzer and the relay as the switch?
