Power distribution board

No, do not use any thread lock / loctite etc. If you want to be sure of avoiding a connection coming loose with vibration then use a 2nd nut as a locking nut on each stud.

Yep,

either a 2nd lock nut and/or a spring/lock washer.

i've used these and never had a problem with them coming lose, not any issues with poor contacts

cheers,
Sam.

A flat washer, spring washer then nut is all that should be required.

Note consider the spring washer to be single use only in heavy vibration areas, and make sure you do not have disimilar metal problems (ie al bar to terminal to wire metals are not compatible).

Also make sure you have fuse(s) at the power source (ie at battery) and local fuses at the board rated according to the equipment attached.

If you use circuit breakers, check the curves are ok for the application. You may find correctly sized fuses are a better option.

Thanks fellows,

Marquis...I am using Bussman circuit breakers, they supply data on response-times so I should be ok there.The take-offs are s/s; if there is any chemistry I expect it will be between the aluminium & terminal for the leads.I will be conformal coating the lot when fitted & tested to reduce potential problems.

Thanks again....eng
