Hi,
Have a general question here that's not in any way a loaded one, more out of curiosity as I always like to learn how things work. Such a thing would actually be impossible now because the switchboards are locked by the electrical company as well.
The builder of the house we live in now, in...

Hi,
I've been doing some revison and came across 2 different equations for voltage drop.
The first one is;
Vd = mV/A x Ib x L divided by 1000
The second one is;
Vd = (R1 + R2) x Ib x Multiplier
The multiplier is to compensate the difference in conductor temperature at the time of the test...

Hello,
3 months ago I installed the Envirovent eco dmev 100HT (humidity & Timer) Bathroom fan for a customer, and have been called back twice since to replace it! has anyone had any similar experiences? any helpful input would be much appreciated
Tested some out side lights today and it triped after 10 seconds. With all loads disconnected.
Don't understand why it would trip after 10 seconds.
Had a slight short on the cable of 95k ohms
Any ideas
I pulled the black lead out my 1553 today and the whole connection came with it! So basically I don't have a tester, any ideas on who I can send it too to have it repaired at a fair price?
Ideally with a quick turnaround!
