RUNNING 3 DIESELS WITH TWIN MOTORS EACH-BREAKER TRIPS ON 180 BRICK EVEN WITH THE SMOKE UNITS OFF ON EACH ENGINE-IS THIS OVERLOADING THE BRICKS ELECTRICAL CAPACITY-I THOUGHT THAT THE ENGINES SHOULD MAX OUT AT 2.6 AMPS EACH WHICH IS UNDER THE 9 AMP BRICKS CAPACITY-ANY IDEAS OR SUGGESTIONS AS TO WHY I AM POPPING THE BREAKER-THANKS

Are you pulling any lighted passenger cars or cabooses? they will increase the current draw.

2.6 X 3 = 7.8 The in-rush or initial start may be more than 9 amps until the units are on. Even at that 2.6 seem high. Eventually you question the thermal magnetic cut out on the PH.
the 2.6 amp usage is from mth tech department-i am also using two lighted cabooses-3 semaphores-one dwarf signal and 4 lighted turnouts-what is puzzling is that i have seen on you tube is 3 lashed up engines with the smoke units on without any elcetrical draw problems.
Truthfully, 2.6A sounds high for the locomotives... I'd measure the current draw of each and see if one is having a problem.
Not if these are PS-2 5V boards. Tom can you confirm if these are older 5V engines?
The 5V diesel engine can draw up to 1.2 to 1.5 amps on sound and lights alone. Smoke an motion can push into the high 2 and low 3 amp level. Pressing the whistle button will spike the amps higher.
PS-2 or 3 engine will draw much less.
Also if you have motors that are failing, or other drag on the engine, motor load can go higher. G
