im new to DC enviroment and was employed to take care of the DC facility.
1 problem i've been facing is the power cable of the rack to the fixed ceeform under raise floor board. i've been tasked to trace each of the in-rack pdu was connected to which ceeform id under raised floor board and documented it down.
Its a nightmare to me as the cable was long and not well managed. some power ceeform can tab frm Row C whereas the rack in Row A. Its painstaking slow progress with risk of tripping the breaker when i manually use hand to trace each cable connection (some pulling cable needed)
my question is, is there any device or equipment out there i can get to assist my task? Perhaps something i tie on the power supply strip in the rack, thn with another item to detect frm fixed ceeform point? something like those datacable tracer kind.
The device you want is called a circuit tracer. You can rent or buy them. A transmitter sends a high frequency signal on the wire that is detectable by the portable receiving unit. Make sure you get one made for the voltage and receptacles you are using. Also, you want one for use with closed circuits.
One problem I've experienced, is where there are multiple power strips in a cabinet, and they enter the raised floor through a single tile cut-out. If the power cords twist around each other, then the high frequency signal of the tracer seems to bleed over from one to the other, and the tracer finds signal on all the power strip cables.
Of course, if two of the power strips run to the same branch circuit, then you also get the high frequency signal bridging between the two power strips via the branch circuit receptacle.
tracing apart, im also looking for tools which can clamp the power strip cable to know how many amp and watt if consuming. however i was being told this is not possible as there are more thn 1 cable inside plus some insulation hence i won't get any reading. is that true?
Diff in tracing power cable
