What is the difference between protective and functional earth?
Wiki User
∙ 11y ago
protective earth (PE) is a conductor, other than a main earthing conductor, connecting any portion of the earthing system to the portion of the electrical installation.
functional earth (FE) is an earthing arrangement provided to ensure correct operation of electrical equipment or to permit reliable and proper functioning of an installation

Can you use the earth wire between room stat and honeywell board as a neutral?
ABSOLUTELY NOT!The protective earth ground wire is only there to provide a low resistance path to ground in the event of a short circuit so as to trip the protective device. Operational current is never, under any circumstances allowed to be passed on earth ground. Use neutral for neutral and ground for ground.CONSULT A QUALIFIED AND LICENSED ELECTRICIAN !!!!
What is the difference between insulation resistance and earth resistance?
insulation resistance can be measured by means of megger, with built in d.c generator. It is measured between the conductor and the earth. earth resistance can be measured by means of earth resistance tester. For good effective earthing, th earth resistance should be of order 0.5 ohm
What is the required color identification for the core of a protective conductor?
In Europe, the standard color for the protective (earth) conductor is a green/yellow stripe, although in most residential two-core (line and neutral; the protective conductor isn't counted) wiring, the protective conductor is bare.
What is the potential difference between earth wire and live wire?
In formal electrical jargon, "potential difference" describes voltage. So a 120 V live wire should have a 120 V potential to the earth wire.AnswerIt depends where you live. In Europe, the nominal potential difference between a line and earth conductor is approx 230 V (approximately, because earth potential might be a little lower than the neutral potential); for North America, the nominal potential difference is about 120 V.
What is the Difference between an active earth pressure and passive earth pressure?
When the wall moves away from the backfill, the earth pressure on the wall decreases. This minimum pressure is called active earth pressure. On the other hand if the wall moves towards the backfill, the earth pressure increases. This maximum pressure is called passive earth pressure.
