Joining Power cables

Joining Power cables

Joining Power cables

(OP)
Hi,

recently relocated a 415V distributional panel. As a consequence that panel is fed from by a sub feeder carrying about 200 A and it goes through an appropriately sized circuit breaker. I am thinking that that breaker is one too many potential failure points.

What do you think? and what is the best connection device to join to power cables.

RE: Joining Power cables

The circuit breaker is a possible point of failure.
Is overcurrent protection required by your electrical code? If so, about your only other choice would be a fused switch.

I don't know how to say if it is a significant risk for your application. It depends on the consequences of a failure. The risk of a failure can be minimized by proper maintenance and periodic testing.
 

RE: Joining Power cables

I can't comment on the sketchy information given.
How about a one line with some sizes and currents.

RE: Joining Power cables

If you must joint the cable a Scotchcast or Raychem type joint is usually the best bet if they are properly used. As Bill says, post a single line diagram with cable sizes and breaker ratings then maybe we can comment further. There's a facility to upload files to a file host just below the 'reply' box.
