Safe-t-cut Consumer Box

Featured Replies

say bloods...

so, here they are, drivin' around the 'hood with the pick up and loud speaker sellin' the product with free installation. Oranges? somtam? never seen a Safe-T-Cut from the back of a pick up but we were in the market for a unit and what the hel_l...6600 baht for a CO6E Consumer Unit & RCBO to replace our fuse box...

a slick outfit but I said let them go ahead and we'll test it...got all the big circuits lined up properly with the breakers after the installation clown was finished yankin' wires all over the place and then I said wadeaminit, how do you simulate a fault to test the actual protection device?...ain't got no DCS settings to override in this case...

anyone seen these guys before? The unit was manufactured in Thailand...

Safe-t-Cut is the original company providing GFI/RCD protection in Thailand and was originally sold in Central type shopping malls. Our unit dates back to 1977. They now make normal breakers/load centers and such but there RCD should always have a test button to check it with. Back in 1977 they used the hot wire in hand and foot on wet tile method as further proof.

:) Don't they do this today anymore? :D

Nope, they all die.

the test button looks good...I'll put the grandson inna baby bath with a hot lead just to prove the integrity...

tutsi to unpopular step daughter: 'hey...step in that baby bath an' touch that wire...'

( :) )

but seriously, folks...I ain't got a lotta confidence in the OEM's testing device; testing of protection devices after installation is quite rigorous in my experience...safe-t-cut claim to have ISO certification but this is a locally manufactured unit and TiT; anyone got a reference regarding actual operation and validation? this is an RCBO device with settings from 6 to 30mA.

I take it that we are working on a differential current protection concept?

got cut off; fcukin' ToT...I meant working from a differential current protection concept...current imbalances usually indicate a serious disturbance hence, the protection...

anyone got any math to put up to illustrate?

I am still alive after 32 years of using said unit. It works. Keep it set at the lowest level that does not cause needless trips. But even 30ma should offer protection for your life.

If you want a quick and dirty test just take a wire from hot side of outlet to ground, keeping yourself insulated, and the Safe-t-cut breaker should be the first to trip; and extremely quickly.

But no mechanical/electronic thing is ever 100% so always use normal caution.

That would be an extremely dangerous test, if the RCD does not trip (or you don't have one) then you've got a dead short L-E, the resulting bang will certainly wake you up.

If you must do this test, use a 15W lamp L-E.

OK, OK...I geddit; the test is not recommended just like power generation generator OEMs don't recommend doing ground fault simulations and indicate that the warranty may be affected...but the integrity of the protection can be demoe'd with jumpered DCS settings

thanks Crossy and Lop for the advice...

what about the price? does 6600 baht sound extreme for a combined consumer unit/RCBO? included installation but the installer was a clown and I hadta line up the circuits with the rated breakers; shouting up the stairs to the step daughter watching the lights on the washing machine, etc...

The price seems reasonable to me; although have not priced recently. In any event should be better then before.
