hi guys i need some help..

my board at home has a 80amp 30ma rcd incomer without a incomer dp switch.

about 10 used circuits ans about 4 spare.

i get some tripping problems so i want to change the rcd as its hard to reset sometimes and crap quality

q- can i use any brand rcd or do i have to use the crap protek one to match the board.
also should i fit a dp incomer as well.

also my combined amps on the whole mcbs add up to about 128 amps! this is on a 80a rcd is this overloaded ..

thanks in advance...
 
Switch is probably not overloaded as diversity comes into play. Although all the breakers add up to 128A you hopefully would not be using any of them to max capacity at any one time if at all.

You can use any RCD as long as it fits, the problem you may have is getting one that does, they have a tendency to be just a little different to make fitting the busbar a problem.

Lenny's idea is better.
 
BG do a tasty board at a good price.
